[PULL REQUEST] NVMe driver updates

[Matthew Wilcox]

Hi Linus,

Lots of exciting new features in the NVM Express driver this time,
including support for emulating SCSI commands, discard support and the
ability to submit per-sector metadata with I/Os.  It's still mostly
bugfixes though!

The following changes since commit a12183c62717ac4579319189a00f5883a18dff08:

  Merge branch 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip (2013-03-25 18:03:34 -0700)

are available in the git repository at:


  git://git.infradead.org/users/willy/linux-nvme.git master
