[Qemu-devel] [PATCH for-4.0 0/3] freeze the backing chain earlier in stream_start()

Posted by Alberto Garcia 5 years, 1 month ago

Hi,

this series fixes the bug that I found the other day and described here:

   https://lists.gnu.org/archive/html/qemu-block/2019-03/msg00764.html
   https://lists.gnu.org/archive/html/qemu-block/2019-03/msg00791.html

Patch 2 is the important one, patch 3 is a test case, and patch 1 will
allow us to detect this kind of errors earlier.

Regards,

Berto
