  sysfs: use sysfs_mutex to protect the sysfs_dirent tree
  sysfs: consolidate sysfs spinlocks
  sysfs: make kobj point to sysfs_dirent instead of dentry
  sysfs: implement sysfs_find_dirent() and sysfs_get_dirent()
  sysfs: implement SYSFS_FLAG_REMOVED flag
  sysfs: rename sysfs_dirent->s_type to s_flags and make room for flags
  sysfs: make sysfs_drop_dentry() access inodes using ilookup()
  sysfs: Fix oops in sysfs_drop_dentry on x86_64
  sysfs: use singly-linked list for sysfs_dirent tree
  sysfs: slim down sysfs_dirent->s_active
  sysfs: move s_active functions to fs/sysfs/dir.c
  sysfs: fix root sysfs_dirent -> root dentry association
  sysfs: use iget_locked() instead of new_inode()
  sysfs: reorganize sysfs_new_indoe() and sysfs_create()
  sysfs: fix parent refcounting during rename and move
