[Qemu-devel] [PATCH 0/2] block/file-posix: Fix xfs_write_zeroes()

[Max Reitz]

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.
