Currently, the fc transport invokes nvme_fc_error_recovery() on every io in which the transport detects an error. Which means: a) it's really noisy on large io loads that all get hit by a link down. b) we repeatively call nvme_stop_queues() even though queues are stopped upon the first error or as first steps of reset_work. Correct by: Errors are only meaningful if the controller is in the LIVE state. Thus, enact the reset_work only if LIVE. If called repeatively, state will have already transitioned. There's no need to stop the queues here. Let the first steps of reset_work do the queue stopping.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
