[Michael Roth]

Hello,

On behalf of the QEMU Team, I'd like to announce the availability of the
third release candidate for the QEMU 2.11 release.  This release is meant
for testing purposes and should not be used in a production environment.

That is from the subsequent patches in the series - you will want to revert
the whole series to test, as the introduced aborts catch the illegal
entries that the reverted patch sidestepped.

The series patches are:

4afeffc
6133b39
a233969
d975301

Of course, these new aborts prevent improper behavior, so we may want to
figure out why this is getting hit.

Unfortunately, I am traveling at the moment (waiting to board my flight), so
will have limited connectivity.

My hunch is the series is a proper fix, but uncovered other latent bugs that
were relying on dangerous behavior.

Yes, I don't know. Either a different fix for your bug, or fixes for the latent
bugs.

Thanks for reporting this, Christian!

I ran qemu-iotests with -raw and -qcow2 to verify that commit
64807cd77938885f681a9a18b5736e923ad50b7c ("Merge remote-tracking
branch 'remotes/cody/tags/block-pull-request' into staging") cause
regressions.  The results were failures in at least 055 109 (-raw) and
020 039 (-qcow2).

I think we should revert commit 64807cd77938885f681a9a18b5736e923ad50b7c.
