Eric Dumazet says: ==================== ipmr: get rid of rwlocks We need to get rid of rwlocks in networking stacks, if read_lock() is (ab)used from softirq context. As discussed recently [1], rwlock are unfair by design in this case, and writers can starve and trigger soft lockups. This series convert ipmr code (both IPv4 and IPv6 families) to RCU and spinlocks.

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.
