treewide: replace obsolete _refok by __ref
There was only one use of __initdata_refok and __exit_refok
__init_refok was used 46 times against 82 for __ref.
Those definitions are obsolete since commit

memstick: don't allocate unused major for ms_block
When alloc_disk(0) is used the ->major number is completely ignored. All devices are allocated with a major of BLOCK_EXT_MAJOR. So remove registration and deregistration of 'major'.

init/Kconfig: make COMPILE_TEST depend on !UML
UML is a bit special since it does not have iomem nor dma. That means a lot of drivers will not build if they miss a dependency on HAS_IOMEM. s390 used to have the same issues but since it gained PCI support UML is the only stranger. We are tired of patching dozens of new drivers after every merge window just to un-break allmod/yesconfig UML builds. One could argue that a decent driver has to know on what it depends and therefore a missing HAS_IOMEM dependency is a clear driver bug. But the dependency not obvious and not everyone does UML builds with COMPILE_TEST enabled when developing a device driver. A possible solution to make these builds succeed on UML would be providing stub functions for ioremap() and friends which fail upon runtime. Another one is simply disabling COMPILE_TEST for UML. Since it is the least hassle and does not force use to fake iomem support let's do the latter.

fs/proc/task_mmu.c: suppress compilation warnings with W=1
Suppress a bunch of warnings of the form:
fs/proc/task_mmu.c: In function 'show_smap_vma_flags':

[ilog2(VM_READ)] = "rd",
^~~~

They happen because of the way we intentionally build the table, so
silence the warning when building with 'make W=1'.

procfs: avoid 32-bit time_t in /proc/*/stat
/proc/stat shows (among lots of other things) the current boottime (i.e. number of seconds since boot). While a 32-bit number is sufficient for this particular case, we want to get rid of the 'struct timespec' suffers from a 32-bit overflow in 2038. This changes the code to use a struct timespec64, which is known to be safe in all cases.

mm: vmscan: fix memcg-aware shrinkers not called on global reclaim
We must call shrink_slab() for each memory cgroup on both global and
memcg reclaim in shrink_node_memcg(). Commit d71df22b55099 accidentally
changed that so that now shrink_slab() is only called with memcg != NULL
on memcg reclaim. As a result, memcg-aware shrinkers (including
dentry/inode) are never invoked on global reclaim. Fix that.

radix-tree: account nodes to memcg only if explicitly requested
Radix trees may be used not only for storing page cache pages, so
unconditionally accounting radix tree nodes to the current memory cgroup
is bad: if a radix tree node is used for storing data shared among
different cgroups we risk pinning dead memory cgroups forever.
So let's only account radix tree nodes if it was explicitly requested by
passing __GFP_ACCOUNT to INIT_RADIX_TREE. Currently, we only want to
account page cache entries, so mark mapping->page_tree so.

mm/kasan: get rid of ->state in struct kasan_alloc_meta
The state of object currently tracked in two places - shadow memory, and the ->state field in struct kasan_alloc_meta. We can get rid of the latter. The will save us a little bit of memory. Also, this allow us to move free stack into struct kasan_alloc_meta, without increasing memory consumption. So now we should always know when the last time the object was freed. This may be useful for long delayed use-after-free bugs. As a side effect this fixes following UBSAN warning: UBSAN: Undefined behaviour in mm/kasan/quarantine.c:102:13 member access within misaligned address ffff88000d1efebc for type 'struct qlist_node' which requires 8 byte alignment Link: http://lkml.kernel.org/r/1470062715-14077-5-git-send-email-aryabinin@virtuozzo.com Reported-by: kernel test robot <xiaolong.ye@intel.com> Signed-off-by: Andrey Ryabinin <aryabinin@virtuozzo.com> Cc: Alexander Potapenko <glider@google.com> Cc: Dmitry Vyukov <dvyukov@google.com> Cc: Christoph Lameter <cl@linux.com> Cc: Pekka Enberg <penberg@kernel.org> Cc: David Rientjes <rientjes@google.com> Cc: Joonsoo Kim <iamjoonsoo.kim@lge.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

Size of slab object already stored in cache->object_size. Note, that kmalloc() internally rounds up size of allocation, so object_size may be not equal to alloc_size, but, usually we don't need to know the exact size of allocated object. In case if we need that information, we still can figure it out from the report. The dump of shadow memory allows to identify the end of allocated memory, and thereby the exact allocation size.

memcg: put soft limit reclaim out of way if the excess tree is empty
We've had a report about soft lockups caused by lock bouncing in the

There are no memcgs created so there cannot be any in the soft limit
excess obviously:
[...]
memory 0 1 1
so all this just seems to be mem_cgroup_largest_soft_limit_node trying
to get spin_lock_irq(&mctz->lock) just to find out that the soft limit
excess tree is empty. This is just pointless wasting of cycles and
cache line bouncing during heavy parallel reclaim on large machines.
The particular machine wasn't very healthy and most probably suffering
from a memory leak which just caused the memory reclaim to trash
heavily. But bouncing on the lock certainly didn't help...
Fix this by optimistic lockless check and bail out early if the tree is
empty. This is theoretically racy but that shouldn't matter all that
much. First of all soft limit is a best effort feature and it is slowly
getting deprecated and its usage should be really scarce. Bouncing on a
lock without a good reason is surely much bigger problem, especially on
large CPU machines.

mm, hugetlb: fix huge_pte_alloc BUG_ON
Zhong Jiang has reported a BUG_ON from huge_pte_alloc hitting when he runs his database load with memory online and offline running in parallel. The reason is that huge_pmd_share might detect a shared pmd which is currently migrated and so it has migration pte which is !pte_huge. There doesn't seem to be any easy way to prevent from the race and in fact seeing the migration swap entry is not harmful. Both callers of huge_pte_alloc are prepared to handle them. copy_hugetlb_page_range will copy the swap entry and make it COW if needed. hugetlb_fault will back off and so the page fault is retries if the page is still under migration and waits for its completion in hugetlb_fault. That means that the BUG_ON is wrong and we should update it. Let's simply check that all present ptes are pte_huge instead.

mm: move swap-in anonymous page into active list
Every swap-in anonymous page starts from inactive lru list's head. It should be activated unconditionally when VM decide to reclaim because page table entry for the page always usually has marked accessed bit. Thus, their window size for getting a new referece is 2 * NR_inactive + NR_active while others is NR_inactive + NR_active. It's not fair that it has more chance to be referenced compared to other newly allocated page which starts from active lru list's head. Johannes: : The page can still have a valid copy on the swap device, so prefering to : reclaim that page over a fresh one could make sense. But as you point : out, having it start inactive instead of active actually ends up giving it : *more* LRU time, and that seems to be without justification. Rik: : The reason newly read in swap cache pages start on the inactive list is : that we do some amount of read-around, and do not know which pages will : get used. : : However, immediately activating the ones that DO get used, like your patch : does, is the right thing to do.

The important bits from the above is that filemap_map_pages() is calling
into the page allocator while holding rcu_read_lock (sleeping is not
allowed inside RCU read-side critical sections).
According to Kirill Shutemov, the prefaulting code in do_fault_around()
is supposed to take care of this, but missing error handling means that
the allocation failure can go unnoticed.
We don't need to return VM_FAULT_OOM (or any other error) here, since we
can just let the normal fault path try again.

ocfs2/dlm: continue to purge recovery lockres when recovery master goes down
We found a dlm-blocked situation caused by continuous breakdown of
recovery masters described below. To solve this problem, we should
purge recovery lock once detecting recovery master goes down.
N3 N2 N1(reco master)
go down
pick up recovery lock and
begin recoverying for N2
go down
pick up recovery
lock failed, then
purge it:
dlm_purge_lockres
->DROPPING_REF is set
send deref to N1 failed,
recovery lock is not purged
find N1 go down, begin
recoverying for N1, but
blocked in dlm_do_recovery
as DROPPING_REF is set:
dlm_do_recovery
->dlm_pick_recovery_master
->dlmlock
->dlm_get_lock_resource
->__dlm_wait_on_lockres_flags(tmpres,

ocfs2/dlm: solve a BUG when deref failed in dlm_drop_lockres_ref
We found a BUG situation that lockres is migrated during deref described
below. To solve the BUG, we could purge lockres directly when other
node says I did not have a ref. Additionally, we'd better purge lockres
if master goes down, as no one will response deref done.
Node 1 Node 2(old master) Node3(new master)
dlm_purge_lockres
send deref to N2
leave domain
migrate lockres to N3
finish migration
send do assert
master to N1
receive do assert msg
form N3, but can not
find lockres because
DROPPING_REF is set,
so the owner is still
N2.
receive deref from N1
and response -EINVAL
because lockres is migrated

ocfs2: retry on ENOSPC if sufficient space in truncate log
The testcase "mmaptruncate" in ocfs2 test suite always fails with ENOSPC error on small volume (say less than 10G). This testcase repeatedly performs "extend" and "truncate" on a file. Continuously, it truncates the file to 1/2 of the size, and then extends to 100% of the size. The main bitmap will quickly run out of space because the "truncate" code prevent truncate log from being flushed by ocfs2_schedule_truncate_log_flush(osb, 1), while truncate log may have cached lots of clusters. So retry to allocate after flushing truncate log when ENOSPC is returned. And we cannot reuse the deleted blocks before the transaction committed. Fortunately, we already have a function to do this - ocfs2_try_to_free_truncate_log(). Just need to remove the "static" modifier and put it into the right place. The "unlock"/"lock" code isn't elegant, but there seems to be no better option.

ocfs2: ensure that dlm lockspace is created by kernel module
We encountered a bug from the customer, the user did a fsck.ocfs2 on the file system and exited unusually, the lockspace (with LVB size = 32) was left in the kernel space, next, the user mounted this file system, the kernel module did not create a new lockspace (LVB size = 64) via calling dlm_new_lockspace() function in mounting stage, just used the existing lockspace, created by the user space tool, this would lead the user was not able to mount this file system from the other nodes, with the error message like: dlm: 032F5......: config mismatch: 64,0 nodeid 177127961: 32,0 (mount.ocfs2,26981,46):ocfs2_dlm_init:2995 ERROR: status = -71 ocfs2_mount_volume:1881 ERROR: status = -71 ocfs2_fill_super:1236 ERROR: status = -71 The user found it very difficult to find the root cause, then, we brought out this patch to relieve such problem. First, we add one more flag in calling dlm_new_lockspace() function, to make sure the lockspace is created by kernel module itself, and this change will not affect the backward compatibility. Second, the obvious error message is reported in the kernel log, let the user be more easy to find the root cause. This patch will be used to insure the dlm lockspace is created by kernel module when mounting a ocfs2 file system. There are two ways to create a lockspace, from user space and kernel space, but the same name lockspaces probably have different lvblen lengths/flags. To avoid this mix using, we add one more flag DLM_LSFL_NEWEXCL, it will make sure the dlm lockspace is created by kernel module when mounting. Secondly, if a user space program (ocfs2-tools) is running on a file system, the user tries to mount this file system in the cluster, DLM module will return a -EEXIST or -EPROTO errno, we should give the user a obvious error message, then, the user can let that user space tool exit before mounting the file system again.

time around, some of the contents worth pointing out is:
- New SoC platforms:
- Freescale i.MX 7Solo
- Broadcom BCM23550
- Cirrus Logic EP7209 and EP7211 (clps711x platforms)_
- Hisilicon HI3519
- Renesas R8A7792
Some of the other delta that is sticking out, line-count wise:
- Exynos moves of IP blocks under an SoC bus, which causes a large delta due
to indentation changes
- A new Tegra K1 board: Apalis
- A bunch of small updates to many Allwinner platforms; new hardware support,
some cleanup, etc.
