Currently, we hold off unregistering with NVMe transport layer until GID_FT or ADISC completes upon receipt of RSCN. In the ADISC discovery routine, for nodes not found in the GID_FT response, the nodes are unregistered from the SCSI transport but not UNREG_RPI'd. Meaning outstanding WQEs continue to be outstanding and were not failed back to the OS. If an NVMe device, this mean there wasn't initial termination of the I/Os so they could be issued on a different NVMe path. Fix by unregistering the RPI so that I/O is cancelled.

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. 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.
