blktests failures with v7.3 kernel

[Shin'ichiro Kawasaki <shinichiro.kawasaki@wdc.com>]

Hi all,

I ran the latest blktests (git hash: 9ad5a10fa8ed) with the v7.3 kernel. I
observed 2 new failures listed below, which were triggered by kernel changes in
v7.3-rcX. The failures reported for v7.3-rc1 kernel [1] were no longer observed.

List of failures
================
#1: nvme/004,031 (rdma transport)
#2: nvme/052

Failure description
===================

#1: nvme/004,031 (rdma transport)

    The test cases nvme/004 and nvme/031 fail occasionally for rdma transport
    due to the lockdep WARN related to the two locks nvmet_config_sem and
    &id_priv->handler_mutex. It is easier to recreate with rxe driver. It is
    rather rare, but the failure is observed with siw driver also.

    The trigger commit was

     2a8513091d2f ("nvme-rdma: parallelize I/O queue allocation and startup")

    in v7.3-rc1. I poseted a fix patch candidate [2].

#2: nvme/052

    When it is repeated several times, the test case nvme/052 fails [3]. The
    trigger commit was

     42b0f5196dc2 ("nvmet: defer setting ns->enabled to false in nvmet_ns_disable()")

    in v7.3-rc6. Nilay kindly provided a fix patch [4].
