Subject: [PATCH 0/2] loop: Better discard for block devices

This series addresses some errors seen when using the loop
device directly backed by a block device. The first change plumbs
out the correct error message, and the second change prevents the
error from occurring in many cases.


Evan Green (2):
  loop: Report EOPNOTSUPP properly
  loop: Better discard support for block devices
