-Subject: [PATCH v5 0/2] loop: Better discard for block devices
-Date: Mon, 6 May 2019 11:27:35 -0700
-Message-Id: <20190506182736.21064-2-evgreen@chromium.org>
-
-This series addresses some errors seen when using the loop
-device directly backed by a block device.
-
-The first change titled "loop: Better discard for block devices"
-plumbs out the correct error message, and the second change prevents
-the error from occurring in many cases.
-
-The errors look like this:
-[ 90.880875] print_req_error: I/O error, dev loop5, sector 0
-
-The errors occur when trying to do a discard or write zeroes operation
-on a loop device backed by a block device that does not support write zeroes.
-Firstly, the error itself is incorrectly reported as I/O error, but is
-actually EOPNOTSUPP. The first patch plumbs out EOPNOTSUPP to properly
-report the error.
-
-The second patch called "loop: Better discard support for block devices"
-prevents these errors from occurring by mirroring the zeroing capabilities
-of the underlying block device into the loop device.
-Before this change, discard was always reported as being supported, and
-the loop device simply turns around and does an fallocate operation on the
-backing device. After this change, backing block devices that do support
-zeroing will continue to work as before, and continue to get all the
-benefits of doing that. Backing devices that do not support zeroing will
-fail earlier, avoiding hitting the loop device at all and ultimately
-avoiding this error in the logs.
-
-I can also confirm that this fixes test block/003 in the blktests, when
-running blktests on a loop device backed by a block device.

+Subject: loop: Better discard support for block devices
+
+If the backing device for a loop device is itself a block device,
+then mirror the "write zeroes" capabilities of the underlying
+block device into the loop device. Copy this capability into both
+max_write_zeroes_sectors and max_discard_sectors of the loop device.
+
+The reason for this is that REQ_OP_DISCARD on a loop device translates
+into blkdev_issue_zeroout(), rather than blkdev_issue_discard(). This
+presents a consistent interface for loop devices (that discarded data
+is zeroed), regardless of the backing device type of the loop device.
+There should be no behavior change for loop devices backed by regular
+files.
+
+This change fixes blktest block/003, and removes an extraneous
+error print in block/013 when testing on a loop device backed
+by a block device that does not support discard.
