2017-05-27T10:07:19+00:00

This will make it easier to implement a sane compat fcntl syscall.

fs: locks: Fix some troubles at kernel-doc comments

2017-05-27T10:07:18+00:00

There are a few syntax violations that cause outputs of
a few comments to not be properly parsed in ReST format.

No functional changes.

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

2017-04-21T14:45:01+00:00

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.

Replace with globally

2016-12-24T19:46:01+00:00

This was entirely automated, using the script by Al:

  PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*'
  sed -i -e "s!$PATT!#include !" \
        $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h)

to do the replacement at the end of the merge window.

locking, fs/locks: Add missing file_sem locks

2016-10-18T10:21:28+00:00

I overlooked a few code-paths that can lead to
locks_delete_global_locks().

fs: Replace current_fs_time() with current_time()

2016-09-28T01:06:22+00:00

current_fs_time() uses struct super_block* as an argument.
As per Linus's suggestion, this is changed to take struct
inode* as a parameter instead. This is because the function
is primarily meant for vfs inode timestamps.
Also the function was renamed as per Arnd's suggestion.

Change all calls to current_fs_time() to use the new
current_time() function instead. current_fs_time() will be
deleted.
