This is a selection of cleanups, renaming of some APIs, and the addition of one simple API (patch 2) which follows an existing pattern. It seemed useful to separate this set from others which will be primarily focussed on adding and using some new APIs. Thanks, NeilBrown [PATCH 1/6] fs/proc: Don't look root inode when creating "self" and [PATCH 2/6] VFS/ovl: add lookup_one_positive_killable() [PATCH 3/6] VFS: discard err2 in filename_create() [PATCH 4/6] VFS: unify old_mnt_idmap and new_mnt_idmap in renamedata [PATCH 5/6] VFS/audit: introduce kern_path_parent() for audit [PATCH 6/6] VFS: rename kern_path_locked() to kern_path_removing()
