Merge branch 'work.lookup' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull more ->lookup() cleanups from Al Viro: "Some ->lookup() instances are still overcomplicating the life for themselves, open-coding the stuff that would be handled by d_splice_alias() just fine. Simplify a couple of such cases caught this cycle and document d_splice_alias() intended use" * 'work.lookup' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: Document d_splice_alias() calling conventions for ->lookup() users. simplify btrfs_lookup() clean erofs_lookup()
