It was found that in some cases host refuses to teardown GPADL for send/ receive buffers (probably when some work with these buffere is scheduled or ongoing). Change the teardown logic to be: 1) Send NVSP_MSG1_TYPE_REVOKE_* messages 2) Close the channel 3) Teardown GPADLs. This seems to work reliably.

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.
