Date: Tue, 3 Nov 2026 12:47:39 +0000 [thread overview]
Message-ID: <010701a1a17370d4-35515fbb-97a0-4f22-b806-de3c8aefa777-000000@eu-central-1.amazonses.com> (raw)
In-Reply-To: <20261103123802.846676-5-andrey.zhadchenko@virtuozzo.com>
> mod_timer() takes an absolute jiffies value, but all callers pass a
> relative one, which is always in the past. The timer fires and re-arms
> on every tick while a write is delayed. It has worked so far because
> pb_timer_func() checks pb->deadline_jiffies each time.

> Fixes: 62e07487348e ("dm: Add push backup driver")
> https://virtuozzo.atlassian.net/browse/VSTOR-152912
