[PATCH RESEND 0/3] xen-block: changes for discard support

[Olaf Hering]

Fix blkfront to handle all sorts of backends.

Also let blkback recognize a xenstore property to disable discard for a
given device. This part requires libxl changes ("discard-enable"):

(This is a resend, this series was already sent 2014-02-10.)

Olaf Hering (3):
  xen-blkfront: remove type check from blkfront_setup_discard
  xen blkif.h: fix comment typo in discard-alignment
  xen/blkback: disable discard feature if requested by toolstack
