...and ensure that such requests are never queued. The MDS has need to know that a request is asynchronous so add flags and proper infrastructure for that. Also, delegated inode numbers and directory caps are associated with the session, so ensure that async requests are always transmitted on the first attempt and are never queued to wait for session reestablishment. If it does end up looking like we'll need to queue the request, then have it return -EJUKEBOX so the caller can reattempt with a synchronous request.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
