As I wrote in one of the emails in this (now huge) thread, I'm fine with
completely dropping that inode->i_refcount check from the
fsnotify_unmount_inodes(). It made sense when it was called before
evict_inodes() but after 1edc8eb2e931 ("fs: call fsnotify_sb_delete after
evict_inodes") the usefulness of this check is rather doubtful. So we can
drop the awkward flag regardless whether we unify evict_inodes() with
fsnotify_unmount_inodes() or not. I have no strong preference whether the
unification happens as part of this patch set or later on so it's up to
Dave as far as I'm concerned.
