We pre-allocate our send-queues and might overflow them in case we have multi work-request operations which tend to occur for large RDMA transfers over devices with limited allowed sg elements. When we get to a queue-full condition we might retry again later, so track our receive buffers so we don't repost them for a retry case.

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.
