Hello all,
Using the kernel v6.15-rc6 and the latest blktests (git hash 613b8377e4d3), I
observe the test case nvme/063 fails with tcp transport. Kernel reported WARN in
blk_mq_unquiesce_queue and KASAN sauf in blk_mq_queue_tag_busy_iter [1]. The
failure is recreated in stable manner on my test nodes.
The test case script had a bug then this failure was not found until the bug get
fixed. I tried the kernel v6.15-rc1, and observed the same failure symptom. This
test case cannot be run with the kernel v6.14, since it does not have secure
concatenation feature.
Actions for fix will be appreciated.
Seems like we are calling 'quiesce' twice:
static void nvme_tcp_teardown_ctrl(struct nvme_ctrl *ctrl, bool shutdown)
{
nvme_tcp_teardown_io_queues(ctrl, shutdown);
nvme_quiesce_admin_queue(ctrl);
nvme_disable_ctrl(ctrl, shutdown);
nvme_tcp_teardown_admin_queue(ctrl, shutdown);
}
static void nvme_tcp_teardown_admin_queue(struct nvme_ctrl *ctrl,
bool remove)
{
nvme_quiesce_admin_queue(ctrl);
blk_sync_queue(ctrl->admin_q);
nvme_tcp_stop_queue(ctrl, 0);
I'll send a patch.
Cheers,
Hannes
