Date: Wed, 4 Nov 2026 08:46:23 +0000 [thread overview]
Message-ID: <010701a1a5bce837-a4927b99-66ce-413f-9e54-fb1d87b2225a-000000@eu-central-1.amazonses.com> (raw)

> ret is still 0 from dm_get_device() when alloc_ordered_workqueue()
> fails, so pb_ctr() frees pb and returns success. The table keeps
> ti->private pointing to freed memory, and pb_dtr() destroys it a
> second time.

> Fixes: 62e07487348e ("dm: Add push backup driver")
