Subject: [Devel] [PATCH hci-8.1 v3 2/6] drivers/md/push_backup: clear pb->alive under pb->lock
Date: Tue, 3 Nov 2026 09:17:48 +0300 [thread overview]
Message-ID: <20261103061752.720813-3-andrey.zhadchenko@virtuozzo.com> (raw)
In-Reply-To: <20261103061752.720813-1-andrey.zhadchenko@virtuozzo.com>
Most other users handle this under the pb->lock so let's
make it a bit more consistent.
