Pull vfs updates from Al Viro:
- more ->d_init() stuff (work.dcache)
- pathname resolution cleanups (work.namei)
- a few missing iov_iter primitives - copy_from_iter_full() and
friends. Either copy the full requested amount, advance the iterator
and return true, or fail, return false and do _not_ advance the
iterator. Quite a few open-coded callers converted (and became more
readable and harder to fuck up that way) (work.iov_iter)
- several assorted patches, the big one being logfs removal
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
logfs: remove from tree
vfs: fix put_compat_statfs64() does not handle errors
namei: fold should_follow_link() with the step into not-followed link
namei: pass both WALK_GET and WALK_MORE to should_follow_link()
namei: invert WALK_PUT logics
namei: shift interpretation of LOOKUP_FOLLOW inside should_follow_link()
namei: saner calling conventions for mountpoint_last()
namei.c: get rid of user_path_parent()
switch getfrag callbacks to ..._full() primitives
make skb_add_data,{_nocache}() and skb_copy_to_page_nocache() advance only on success
[iov_iter] new primitives - copy_from_iter_full() and friends
don't open-code file_inode()
ceph: switch to use of ->d_init()
ceph: unify dentry_operations instances
lustre: switch to use of ->d_init()

Direct Access (DAX) can be used on memory-backed block devices.
|
|
If the block device supports DAX and the filesystem supports DAX,
|
|
then you can avoid using the pagecache to buffer I/Os. Turning
|
|
on this option will compile in support for DAX; you will need to
|
|
mount the filesystem using the -o dax option.

If you do not have a block device that is capable of using this,

Tmpfs is a file system which keeps all files in virtual memory.
|
|
|
|
Everything in tmpfs is temporary in the sense that no files will be
|
|
created on your hard drive. The files live in memory and swap
|
|
space. If you unmount a tmpfs instance, everything stored therein is
|
|
lost.

POSIX Access Control Lists (ACLs) support additional access rights

for users and groups beyond the standard owner/group/world scheme,

and this option selects support for ACLs specifically for tmpfs
|
|
filesystems.
|
|
|
|
If you've selected TMPFS, it's possible that you'll also need
|
|
this option as there are a number of Linux distros that require
|
|
POSIX ACL support under /dev for certain features to work properly.
|
|
For example, some distros need this feature for ALSA-related /dev
|
|
files for sound to work properly. In short, if you're not sure,
|
|
say Y.
