modprobe -r lpfc produces the following: Call Trace: __blk_mq_run_hw_queue+0xa2/0xb0 __blk_mq_delay_run_hw_queue+0x9d/0xb0 ? blk_mq_hctx_has_pending+0x32/0x80 blk_mq_run_hw_queue+0x50/0xd0 blk_mq_sched_insert_request+0x110/0x1b0 blk_execute_rq_nowait+0x76/0x180 nvme_keep_alive_work+0x8a/0xd0 [nvme_core] process_one_work+0x17f/0x440 worker_thread+0x126/0x3c0 ? manage_workers.isra.24+0x2a0/0x2a0 kthread+0xd1/0xe0 ? insert_kthread_work+0x40/0x40 ret_from_fork_nospec_begin+0x21/0x21 ? insert_kthread_work+0x40/0x40 However, rmmod lpfc would run correctly. When an nvme remoteport is unregistered with the host nvme transport, it needs to set the remoteport->dev_loss_tmo value 0 to indicate an immediate termination of device loss and prevent any further keep alives to that rport. The driver was never setting dev_loss_tmo causing the nvme transport to continue to send the keep alive.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
