Subject: [PULL 38/50] block/mirror.c: use of job helpers in drivers
Date: Fri,  7 Oct 2022 12:47:40 +0200	[thread overview]
Message-ID: <20221007104752.141361-39-kwolf@redhat.com> (raw)
In-Reply-To: <20221007104752.141361-1-kwolf@redhat.com>

From: Emanuele Giuseppe Esposito <eesposit@redhat.com>

Once job lock is used and aiocontext is removed, mirror has
to perform job operations under the same critical section,
Note: at this stage, job_{lock/unlock} and job lock guard macros
are *nop*.
