Date: Tue, 3 Nov 2026 08:12:57 +0000 [thread overview]
Message-ID: <010701a1a077f12a-65922957-b988-469b-8393-4801ee57f8fb-000000@eu-central-1.amazonses.com> (raw)
In-Reply-To: <20261103080358.723186-5-andrey.zhadchenko@virtuozzo.com>
> mod_timer() takes an absolute jiffies value, but both callers pass a
> relative one. After about 5 min uptime this causes the timer to fire
> and re-arm on every tick. This has not exploded because we still have
> checked pb->deadline_jiffies each time.

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