Linus Torvalds ffc766b31e This is an irregular pull request for sending a lockdep patch.
Peter Zijlstra asked us to find bad annotation that blows up the lockdep
 storage [1][2][3] but we could not find such annotation [4][5], and
 Peter cannot give us feedback any more [6]. Since we tested this patch
 on linux-next.git without problems, and keeping this problem unresolved
 discourages kernel testing which is more painful, I'm sending this patch
 without forever waiting for response from Peter.

Pull lockdep capacity limit updates from Tetsuo Handa:
 "syzbot is occasionally reporting that fuzz testing is terminated due
  to hitting upper limits lockdep can track.

  Analysis via /proc/lockdep* did not show any obvious culprits, allow
  tuning tracing capacity constants"

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.
