task_work's are typically queued up from IRQ/softirq potentially by a random CPU like in case of networking. Batch ctx fields bouncing as this into a separate cache line. We also move ->cq_timeouts there because waiters have to read and check it. We can also conditionally hide ->cq_timeouts in the future from the CQ wait path as a not really useful rudiment.

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.
