Patch series "kcov: collect coverage from usb soft interrupts", v4. This patchset extends kcov to allow collecting coverage from soft interrupts and then uses the new functionality to collect coverage from USB code. This has allowed to find at least one new HID bug [1], which was recently fixed by Alan [2]. [1] https://syzkaller.appspot.com/bug?extid=09ef48aa58261464b621 [2] https://patchwork.kernel.org/patch/11283319/ Any subsystem that uses softirqs (e.g. timers) can make use of this in the future. Looking at the recent syzbot reports, an obvious candidate is the networking subsystem [3, 4, 5 and many more].

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.
