Subject: [PATCH 0/3] Fix active mirror dead-lock
Date: Sat, 3 Jul 2021 00:16:33 +0300 [thread overview]
Message-ID: <20210702211636.228981-1-vsementsov@virtuozzo.com> (raw)
Hi all!
We've faced a dead-lock in active mirror in our Rhev-8.4 based Qemu
build. And it's reproducible on master too.
Vladimir Sementsov-Ogievskiy (3):
block/mirror: set .co for active-write MirrorOp objects
iotest 151: add test-case that shows active mirror dead-lock
block/mirror: fix active mirror dead-lock in mirror_wait_on_conflicts
block/mirror.c | 13 +++++++++
