Subject: [PATCH 0/3] fix potential infinite loop in debugfs_remove_recursive

The first patch add a new enum type for 'dentry_d_lock_class'.The second
patch use the new enum type in 'simple_empty' to avoid confusion for
lockdep. The last patch fix potential infinite loop in
debugfs_remove_recursive by using 'simple_empty' instead of 'list_empty'.

yu kuai (3):
  dcache: add a new enum type for 'dentry_d_lock_class'
  fs/libfs.c: use 'spin_lock_nested' when taking 'd_lock' for dentry in
    simple_empty
  debugfs: fix potential infinite loop in debugfs_remove_recursive
