  functionfs, gadgetfs: use simple_recursive_removal() (2025-07-02 22:36:52 -0400)

----------------------------------------------------------------
        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.

----------------------------------------------------------------
Al Viro (9):
      simple_recursive_removal(): saner interaction with fsnotify
      better lockdep annotations for simple_recursive_removal()
      add locked_recursive_removal()
      spufs: switch to locked_recursive_removal()
      binfmt_misc: switch to locked_recursive_removal()
      pstore: switch to locked_recursive_removal()
      fuse_ctl: use simple_recursive_removal()
      kill binderfs_remove_file()
      functionfs, gadgetfs: use simple_recursive_removal()
