blktests failures with v6.10 kernel
Hi all,
I ran the latest blktests (git hash: f79783b44a5b) with the v6.10 kernel. Also I
checked the CKI project run results. In total, four failures were observed, as
listed below.
The nvme/050 failure observed with the kernel v6.10-rc1 [1] was fixed and no
longer observed. Good.

List of failures
================

Failure description
===================
#1: nvme/041 (fc transport)
With the trtype=fc configuration, nvme/041 fails:

nvme/044 had same failure symptom until the kernel v6.9. A solution was
suggested and discussed in Feb/2024 [2].

#2: dm/002
When udev accesses the test target dm-dust device, "dmsetup remove" by the
test case fails. A fix patch for blktests is posted [3].

#3: srp/002 (siw driver)
During the fix confirmation work of srp/002 hang with rxe driver, KASAN slab-
use-after-free was observed with siw driver [4]. Bart identified the resource
freed under use (thanks!). His kernel fix patch is queued for v6.11-rc1 [5].

#4: nbd/001,002
The CKI project reported that nbd/001 and nbd/002 fail occasionally. The
failure cause was the race between nbd-server port readiness and nbd-client
connect. A fix patch for blktests is posted [6].
