Paolo Abeni says: ==================== mptcp: refactor token container Currently the msk sockets are stored in a single radix tree, protected by a global spin_lock. This series moves to an hash table, allocated at boot time, with per bucker spin_lock - alike inet_hashtables, but using a different key: the token itself. The above improves scalability, as write operations will have a far later chance to compete for lock acquisition, allows lockless lookup, and will allow easier msk traversing - e.g. for diag interface implementation's sake. This also introduces trivial, related, kunit tests and move the existing in kernel's one to kunit. v1 -> v2: - fixed a few extra and sparse warns ==================== Signed-off-by: David S.

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.
