This is similar to942491c9e6("xfs: fix AIM7 regression") Apparently our current rwsem code doesn't like doing the trylock, then lock for real scheme. So change our read/write methods to just do the trylock for the RWF_NOWAIT case. We don't need a check for IOCB_NOWAIT and !direct-IO because it is checked in generic_write_checks().

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.
