Properly plumb out EOPNOTSUPP from loop driver operations, which may
get returned when for instance a discard operation is attempted but not
supported by the underlying block device. Before this change, everything
was reported in the log as an I/O error, which is scary and not
helpful in debugging.

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.

From 3117c3f45edbcc269baaebd3d13f39b7bf884aa6 Mon Sep 17 00:00:00 2001
From: Evan Green <evgreen@chromium.org>

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.
