Subject: [Devel] [PATCH hci-8.1 v5 3/7] drivers/md/push_backup: clear pb->alive under pb->lock
Date: Tue, 3 Nov 2026 15:37:58 +0300 [thread overview]
Message-ID: <20261103123802.846676-4-andrey.zhadchenko@virtuozzo.com> (raw)
In-Reply-To: <20261103123802.846676-1-andrey.zhadchenko@virtuozzo.com>
Most other users handle this under the pb->lock so let's
make it a bit more consistent.
