Current fc transport code, on io termination, is calling nvme_cleanup_cmd() followed by the transport dma unmap routine which also calls nvme_cleanup_cmd(). Which means two kfrees occur on the same address, raising havoc. This resulted in odd data errors, effectively corruption.. Fix by removing the extraneous double calls. Call now occurs only in teardown paths and as part of dma unmap routine. Signed-off-by: James Smart <james.smart@broadcom.com> Reviewed-by: Ewan D.

README
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.
