[ Upstream commit 27cd1bf1240d482e4f02ca4f9812e748f3106e4f ]
incidentally, securityfs_recursive_remove() is broken without that - it leaks dentries, since simple_recursive_removal() does not expect anything of that sort. It could be worked around by dput() in remove_one() callback, but it's easier to just drop that double-get stuff.
