commit e74ead135bc4459f7d40b1f8edab1333a28b54e8 upstream. Don't check if we can do nowait before arming apoll, there are several reasons for that. First, we don't care much about files that don't support nowait. Second, it may be useful -- we don't want to be taking away extra workers from io-wq when it can go in some async. Even if it will go through io-wq eventually, it make difference in the numbers of workers actually used. And the last one, it's needed to clean nowait in future commits.

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.
