Subject: [Qemu-devel] [PATCH 0/2] block/file-posix: Fix xfs_write_zeroes()
Date: Thu, 22 Aug 2019 18:26:16 +0200 [thread overview]
Message-ID: <20190822162618.27670-1-mreitz@redhat.com> (raw)
Lukàš ran over a nasty regression in our xfs_write_zeroes() function
(sorry, my fault) made apparent by a recent patch from Anton that makes
qcow2 images heavily exercise the offending code path.
This series fixes the bug and adds a test to prevent it from
reoccurring.

iotests: Test reverse sub-cluster qcow2 writes
