Subject: [PATCH v3 19/47] filelock: convert more internal functions to use
file_lock_core
Convert more internal fs/locks.c functions to take and deal with struct
file_lock_core instead of struct file_lock:
- locks_dump_ctx_list
- locks_check_ctx_file_list
- locks_release_private
- locks_owner_has_blockers
