[Qemu-devel] [PATCH] qemu-iotests: Fix test 038

[Max Reitz]

Test 038 uses asynchronous I/O, resulting (potentially) in a different
output for every run (regarding the order of the I/O accesses). This can
be fixed by simply sorting the I/O access messages, since their order is
irrelevant anyway (for this asynchonous I/O).
