time: delete current_fs_time()

All uses of the current_fs_time() function have been replaced by other time interfaces. And, its use cases can be fulfilled by current_time() or ktime_get_* variants.

fs: semove set but not checked AOP_FLAG_UNINTERRUPTIBLE flag

2017-05-09T00:15:14Z

Commit afddba49d18f ("fs: introduce write_begin, write_end, and perform_write aops") introduced AOP_FLAG_UNINTERRUPTIBLE flag which was checked in pagecache_write_begin(), but that check was removed by 4e02ed4b4a2f ("fs: remove prepare_write/commit_write"). Between these two commits, commit d9414774dc0c ("cifs: Convert cifs to new aops.") added a check in cifs_write_begin(), but that check was soon removed by commit a98ee8c1c707 ("[CIFS] fix regression in cifs_write_begin/cifs_write_end"). Therefore, AOP_FLAG_UNINTERRUPTIBLE flag is checked nowhere. Let's remove this flag. This patch has no functionality changes.

2017-05-04T23:52:03Z

stat/lstat/fstatat need to pass AT_NO_AUTOMOUNT to vfs_statx() as the pre-statx code didn't set LOOKUP_AUTOMOUNT, even though fstatat() accepted the AT_NO_AUTOMOUNT flag.

fs: constify tree_descr arrays passed to simple_fill_super()

2017-04-27T03:54:06Z

simple_fill_super() is passed an array of tree_descr structures which describe the files to create in the filesystem's root directory. Since these arrays are never modified intentionally, they should be 'const' so that they are placed in .rodata and benefit from memory protection. This patch updates the function signature and all users, and also constifies tree_descr.name. Signed-off-by: Eric Biggers Signed-off-by: Al Viro

locks: Set FL_CLOSE when removing flock locks on close()

2017-04-21T14:45:01Z

Set FL_CLOSE in fl_flags as in locks_remove_posix() when clearing locks. NFS will check for this flag to ensure an unlock is sent in a following patch. Fuse handles flock and posix locks differently for FL_CLOSE, and so requires a fixup to retain the existing behavior for flock.
