From: Miklos Szeredi <mszer...@suse.cz>
Do have_submounts(), shrink_dcache_parent() and d_drop() atomically.
check_submounts_and_drop() can deal with negative dentries and
non-directories as well.
Non-directories can also be mounted on. And just like directories we don't
want these to disappear with invalidation.
