This is a revised selection of cleanups and API renaming which continues my work to centralise locking of create/remove/rename operations. I've removed a procfs cleanup which conflicts slightly with some of Al's work, and added more renaming, and have added some more places that use simple_start_creating(). Thanks, NeilBrown [PATCH v2 1/7] VFS/ovl: add lookup_one_positive_killable() [PATCH v2 2/7] VFS: discard err2 in filename_create() [PATCH v2 3/7] VFS: unify old_mnt_idmap and new_mnt_idmap in [PATCH v2 4/7] VFS/audit: introduce kern_path_parent() for audit [PATCH v2 5/7] VFS: rename kern_path_locked() and related functions. [PATCH v2 6/7] VFS: introduce simple_end_creating() and [PATCH v2 7/7] Use simple_start_creating() in various places.
