if a nvme command is issued with an opcode that is not supported by the target (example: opcode 21 - detach namespace), the target crashes due to a null pointer. nvmet_req_init() detects the bad opcode and immediately calls the nvme command done routine with an error status, allowing the transport to send the response. However, the FC transport was aborting the command on error, so the abort freed the lldd point, but the rsp transmit path referenced it psot the free. Fix by removing the abort call on nvmet_req_init() failure. The completion response will be sent with an error status code. As the completion path will terminate the io, ensure the data_sg lists show an unused state so that teardown paths are successful.

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.
