[Qemu-devel] [PATCH 00/10] block: Op blocker fixes

[Kevin Wolf]

This series fixes a few problems introduced recently with the op blocker
series. It includes mainly fix for cases where qemu would abort()
instead of doing proper error handling previously. These changes also
happen to result in more complete and correct permission checking.
