Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux
fe99a4f4d6
In order to enable the queuing of kthread work items from hardirq context even when PREEMPT_RT_FULL is enabled, convert the worker spin_lock to a raw_spin_lock. This is only acceptable to do because the work performed under the lock is well-bounded and minimal.

README
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.
