Merge branch 'for-linus' of git://git.kernel.dk/linux-block 

Pull block driver update from Jens Axboe:
 "Distilled down variant, the rest will pass over to 3.8.  I pulled it
  into the for-linus branch I had waiting for a pull request as well, in
  case you are wondering why there are new entries in here too.  This
  also got rid of two reverts and the ones of the mtip32xx patches that
  went in later in the 3.6 cycle, so the series looks a bit cleaner."

* 'for-linus' of git://git.kernel.dk/linux-block:
  loop: Make explicit loop device destruction lazy
  mtip32xx:Added appropriate timeout value for secure erase
  xen/blkback: Change xen_vbd's flush_support and discard_secure to have type unsigned int, rather than bool
  cciss: select CONFIG_CHECK_SIGNATURE
  cciss: remove unneeded memset()
  xen/blkback: use kmem_cache_zalloc instead of kmem_cache_alloc/memset
  pktcdvd: update MAINTAINERS
  floppy: remove dr, reuse drive on do_floppy_init
  floppy: use common function to check if floppies can be registered
  floppy: properly handle failure on add_disk loop
  floppy: do put_disk on current dr if blk_init_queue fails
  floppy: don't call alloc_ordered_workqueue inside the alloc_disk loop
  xen/blkback: Fix compile warning
  block: Add blk_rq_pos(rq) to sort rq when plushing
  drivers/block: remove CONFIG_EXPERIMENTAL
  block: remove CONFIG_EXPERIMENTAL
  vfs: fix: don't increase bio_slab_max if krealloc() fails
  blkcg: stop iteration early if root_rl is the only request list
  blkcg: Fix use-after-free of q->root_blkg and q->root_rl.blkg
