[ Upstream commits9392a27d88andff002b3018] Ensure that the async work grabs ->fs from the queueing task if the punted commands needs to do lookups. We don't have these two commits in 5.4-stable:ff002b30189392a27d88because they don't apply with the rework that was done in how io_uring handles offload. Since there's no io-wq in 5.4, it doesn't make sense to do two patches. I'm attaching my port of the two for 5.4-stable, it's been tested. Please queue it up for the next 5.4-stable, thanks!

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.
