Subject: [PULL REQUEST] NVMe driver updates


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
