Chris Wilson f4d57d838c drm/i915: Allow interrupts when taking the timeline->mutex
Before we commit ourselves to writing commands into the
ringbuffer and submitting the request, allow signals to interrupt
acquisition of the timeline mutex. We allow ourselves to be interrupted
at any time later if we need to block for space in the ring, anyway.

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.
