Pull simple_recursive_removal() update from Al Viro: "Removing subtrees of kernel filesystems is done in quite a few places; unfortunately, it's easy to get wrong. A number of open-coded attempts are out there, with varying amount of bogosities. simple_recursive_removal() had been introduced for doing that with all precautions needed; it does an equivalent of rm -rf, with sufficient locking, eviction of anything mounted on top of the subtree, etc. This series converts a bunch of open-coded instances to using that" * tag 'pull-simple_recursive_removal' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: functionfs, gadgetfs: use simple_recursive_removal() kill binderfs_remove_file() fuse_ctl: use simple_recursive_removal() pstore: switch to locked_recursive_removal() binfmt_misc: switch to locked_recursive_removal() spufs: switch to locked_recursive_removal() add locked_recursive_removal() better lockdep annotations for simple_recursive_removal() simple_recursive_removal(): saner interaction with fsnotify
