[Qemu-devel] [PATCH] qemu-iotests: update 185 output
Posted by Stefan Hajnoczi 6 years ago
Commit 4486e89c219c0d1b9bd8dfa0b1dd5b0d51ff2268 ("vl: introduce
vm_shutdown()") added a bdrv_drain_all() call.  As a side-effect of the
drain operation the block job iterates one more time than before.  The
185 output no longer matches and the test is failing now.

It may be possible to avoid the superfluous block job iteration, but
that type of patch is not suitable late in the QEMU 2.12 release cycle.

This patch simply updates the 185 output file.  The new behavior is
correct, just not optimal, so make the test pass again.

Fixes: 4486e89c219c0d1b9bd8dfa0b1dd5b0d51ff2268 ("vl: introduce vm_shutdown()")

Do you want to update the comment in the 185 test case code that
explains which values we expect?

Need we add the comment in 185.out that this change is to make the test pass for the superfluous block job iteration?
