Subject: [PATCH 0/3]block/loop: handle discard/zeroout error

Fix some problems when setting up loop device with a block device as back file
and create/mount ext4 in the loop device.

BTW: blkdev_issue_zeroout retries if we immediately find the device doesn't
support zeroout, but it doesn't retry if submit_bio_wait returns -EOPNOTSUPP.
Is this correct behavior?

Thanks,
Shaohua

  block/loop: don't hijack error number
  block/loop: use FALLOC_FL_ZERO_RANGE for REQ_OP_WRITE_ZEROES
  block/loop: suppress discard IO error message
