commit df180e65305f8c1e020d54bfc2132349fd693de1 upstream. Several issues with this change: * The analysis is flawed and it's unclear what problem is being fixed. There is no difference between wait_event_freezable_timeout() and wait_event_timeout() with respect to device interrupts. And of course "the interrupt notifying the finish of an operation happens during wait_event_freezable_timeout()" -- that's how it's supposed to work. * The link at the "Closes:" tag appears to be an unrelated use-after-free in idxd. * It introduces a regression: dmatest threads are meant to be freezable and this change breaks that.

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.
