From: Mark McLoughlin <markmc@redhat.com>
Subject: [PATCH] block: silently error unsupported empty barriers too
With 2.6.31-rc5 in a KVM guest using dm and virtio_blk, we see the
following errors:
end_request: I/O error, dev vda, sector 0
end_request: I/O error, dev vda, sector 0
The errors go away if dm stops submitting empty barriers, by reverting:
commit 52b1fd5a27c625c78373e024bf570af3c9d44a79
Author: Mikulas Patocka <mpatocka@redhat.com>
dm: send empty barriers to targets in dm_flush
We should error all barriers, even empty barriers, on devices like
virtio_blk which don't support them.
