  "message": "[PATCH] lockdep: annotate blkdev nesting\n\nTeach special (recursive) locking code to the lock validator.\n\nEffects on non-lockdep kernels:\n\n- the introduction of the following function variants:\n\n  extern struct block_device *open_partition_by_devnum(dev_t, unsigned);\n\n  extern int blkdev_put_partition(struct block_device *);\n\n  static int\n  blkdev_get_whole(struct block_device *bdev, mode_t mode, unsigned flags);\n\n which on non-lockdep are the same as open_by_devnum(), blkdev_put()\n and blkdev_get().\n\n- a subclass parameter to do_open(). [unused on non-lockdep]\n\n- a subclass parameter to __blkdev_put(), which is a new internal\n  function for the main blkdev_put*() functions. [parameter unused\n  on non-lockdep kernels, except for two sanity check WARN_ON()s]\n\nthese functions carry no semantical difference - they only express\nobject dependencies towards the lockdep subsystem.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nCc: Neil Brown \u003cneilb@cse.unsw.edu.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
