mainlining shenanigans
c058ecf6e4
Only insert our special drain CQEs to support ib_drain_sq/rq() after
the wq is flushed. Otherwise, existing but not yet polled CQEs can be
returned out of order to the user application. This can happen when the
QP has exited RTS but not yet flushed the QP, which can happen during
a normal close (vs abortive close).
In addition never count the drain CQEs when determining how many CQEs
need to be synthesized during the flush operation. This latter issue
should never happen if the QP is properly flushed before inserting the
drain CQE, but I wanted to avoid corrupting the CQ state. So we handle
it and log a warning once.

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.
