[Qemu-devel] [PATCH v2 0/4] Separate QUORUM_REPORT_BAD events according to their node name |

QUORUM_REPORT_BAD events are limited to a maximum rate of 1 per
second. While this is not a problem in itself, this means that an
error in one a Quorum child will mask errors in the other children if
they happen within the same 1 second interval.
This series fixes that problem by separating these events in different
queues if they come from different nodes. Once we add the 'type' field
to QUORUM_REPORT_BAD we will also be able to classify them according
to the type if we want.
In addition to the above, this series also fixes a crash that happens
if there's an I/O error in one of the children. This is serious enough
so I'll send the patch to fix this crash to qemu-stable as well.
Regards,
Berto
