v2 cover Minor cleanup for locks API

NFS has recently been moving things around to cope with the situation where a struct file may not be available during an unlock. That work has presented an opportunity to do a minor cleanup on the locks API.

Users of posix_lock_file_wait() (for FL_POSIX style locks) and flock_lock_file_wait() (for FL_FLOCK style locks) can instead call locks_lock_file_wait() for both lock types. Because the passed-in file_lock specifies its own type, the correct function can be selected on behalf of the user.

This work allows further cleanup within NFS and lockd which will be submitted separately.

Changes in v2:
- fix typo that caused build failure for CONFIG_FILE_LOCKS=n
- make posix_lock_inode_wait and flock_lock_inode_wait static
- trimmed away a number of distro-lists to minimize cross-posting

Benjamin Coddington (3):
locks: introduce locks_lock_inode_wait()
Move locks API users to locks_lock_inode_wait()
locks: cleanup posix_lock_inode_wait and flock_lock_inode_wait

PATCH v2 2/3 Move locks API users to locks_lock_inode_wait()

Instead of having users check for FL_POSIX or FL_FLOCK to call the correct locks API function, use the check within locks_lock_inode_wait(). This allows for some later cleanup.

PATCH v2 1/3 locks: introduce locks_lock_inode_wait()

In reply to Benjamin Coddington

Users of the locks API commonly call either posix_lock_file_wait() or flock_lock_file_wait() depending upon the lock type. Add a new function locks_lock_inode_wait() which will check and call the correct function for the type of lock passed in.

NFS has recently been moving things around to cope with the situation where a struct file may not be available during an unlock. That work has presented an opportunity to do a minor cleanup on the locks API.

Quoted 8 lines

Users of posix_lock_file_wait() (for FL_POSIX style locks) and flock_lock_file_wait() (for FL_FLOCK style locks) can instead call locks_lock_file_wait() for both lock types. Because the passed-in file_lock specifies its own type, the correct function can be selected on behalf of the user.

This work allows further cleanup within NFS and lockd which will be submitted separately.

Looks good to me.--b.

NFS has recently been moving things around to cope with the situation where a struct file may not be available during an unlock. That work has presented an opportunity to do a minor cleanup on the locks API.

Users of posix_lock_file_wait() (for FL_POSIX style locks) and flock_lock_file_wait() (for FL_FLOCK style locks) can instead call locks_lock_file_wait() for both lock types. Because the passed-in file_lock specifies its own type, the correct function can be selected on behalf of the user.

This work allows further cleanup within NFS and lockd which will be submitted separately.

Changes in v2:
- fix typo that caused build failure for CONFIG_FILE_LOCKS=n
- make posix_lock_inode_wait and flock_lock_inode_wait static
- trimmed away a number of distro-lists to minimize cross-posting

Looks good to me too. I'll plan to merge them for v4.4.

Thanks!
