Pull RCU fix from Paul McKenney: "This fixes a pair of bugs in which an improbable but very real sequence of events can cause kfree_rcu() to be a bit too quick about freeing the memory passed to it. It turns out that this pair of bugs is about two years old, and so this is not a v6.3 regression. However: (1) It just started showing up in the wild and (2) Its consequences are dire, so its fix needs to go in sooner rather than later. Testing is of course being upgraded, and the upgraded tests detect this situation very quickly. But to the best of my knowledge right now, the tests are not particularly urgent and will thus most likely show up in the v6.5 merge window (the one after this coming one). Kudos to Ziwei Dai and his group for tracking this one down the hard way!" * tag 'urgent-rcu.2023.04.07a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu: rcu/kvfree: Avoid freeing new kfree_rcu() memory after old grace period
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.
