60e2b00ea2 rtc-puv3: using module_platform_driver()
This patch converts the driver to use the module_platform_driver()
macro which makes the code smaller and a bit simpler.

7037bd803e unicore32: Use set_current_blocked()
As described in e6fa16ab ("signal: sigprocmask() should do
retarget_shared_pending()") the modification of current->blocked is
incorrect as we need to check whether the signal we're about to block
is pending in the shared queue.

0ce8c0109f ext[34]: avoid i_nlink warnings triggered by drop_nlink/inc_nlink kludge in symlink()
Both ext3 and ext4 put the half-created symlink inode into the orphan list
for a while (see the comment in ext[34]_symlink() for gory details).  Then,
if everything went fine, they pull it out of the orphan list and bump the
link count back to 1.  The thing is, inc_nlink() is going to complain about
seeing somebody changing i_nlink from 0 to 1.  With a good reason, since
normally something like that is a bug.  Explicit set_nlink(inode, 1) does
the same thing as inc_nlink() here, but it does *not* complain - exactly
because it should be usable in strange situations like this one.

da01636a65 exofs: oops after late failure in mount
We have already set ->s_root, so ->put_super() is going to be called.

5b5f956035 functionfs: unfuck failure exits on mount
* if you do dput() of root dentry, do *not* follow that with iput() of root
inode.
* while we are at it, don't do that dput() at all - you are leaving the pointer
in ->s_root and your ->kill_sb() will be very unhappy with that.  It will do
proper dput(), though, so the easiest way is to leave that to it entirely.
* freeing ->s_fs_info is also best left to ->kill_sb() (which will do it
anyway), especially since we leave the pointer in place.
* that xchg() in ->kill_sb() is not a bug per se, but it's a plain and simple
masturbation with fewer excuses than Onan had...

a0e86bd425 audit: always follow va_copy() with va_end()
A call to va_copy() should always be followed by a call to va_end() in
the same function.  In kernel/autit.c::audit_log_vformat() this is not
always done.  This patch makes sure va_end() is always called.

7dd72f5189 drivers/scsi/aacraid/commctrl.c: fix mem leak in aac_send_raw_srb()
We leak in drivers/scsi/aacraid/commctrl.c::aac_send_raw_srb() :

We allocate memory:

	...
	struct user_sgmap* usg;
	usg = kmalloc(actual_fibsize - sizeof(struct aac_srb)
	  + sizeof(struct sgmap), GFP_KERNEL);

and then neglect to free it:

	...
	for (i = 0; i < usg->count; i++) {
		u64 addr;
		void* p;
		if (usg->sg[i].count >
		    ((dev->adapter_info.options &
		     AAC_OPT_NEW_COMM) ?
		      (dev->scsi_host_ptr->max_sectors << 9) :
		      65536)) {
			rcode = -EINVAL;
			goto cleanup;
	... this 'goto' makes 'usg' go out of scope and leak the memory we
	    allocated.

Other exits properly kfree(usg), it's just here it is neglected.

7ada4db886 vfs: count unlinked inodes
Add a new counter to the superblock that keeps track of unlinked but
not yet deleted inodes.

Do not WARN_ON if set_nlink is called with zero count, just do a
ratelimited printk.  This happens on xfs and probably other
filesystems after an unclean shutdown when the filesystem reads inodes
which already have zero i_nlink.  Reported by Christoph Hellwig.

4ed5e82fe7 vfs: protect remounting superblock read-only
Currently remouting superblock read-only is racy in a major way.

With the per mount read-only infrastructure it is now possible to
prevent most races, which this patch attempts.

Before starting the remount read-only, iterate through all mounts
belonging to the superblock and if none of them have any pending
writes, set sb->s_readonly_remount.  This indicates that remount is in
progress and no further write requests are allowed.  If the remount
succeeds set MS_RDONLY and reset s_readonly_remount.

If the remounting is unsuccessful just reset s_readonly_remount.
This can result in transient EROFS errors, despite the fact the
remount failed.  Unfortunately hodling off writes is difficult as
remount itself may touch the filesystem (e.g. through load_nls())
which would deadlock.

A later patch deals with delayed writes due to nlink going to zero.
