Merge branch 'work.recursive_removal' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs recursive removal updates from Al Viro: "We have quite a few places where synthetic filesystems do an equivalent of 'rm -rf', with varying amounts of code duplication, wrong locking, etc. That really ought to be a library helper. Only debugfs (and very similar tracefs) are converted here - I have more conversions, but they'd never been in -next, so they'll have to wait" * 'work.recursive_removal' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: simple_recursive_removal(): kernel-side rm -rf for ramfs-style filesystems
