Linus Torvalds 5edc6bb321 Tracing fixes for 6.6-rc2:
- Fix the "bytes" output of the per_cpu stat file
   The tracefs/per_cpu/cpu*/stats "bytes" was giving bogus values as the
   accounting was not accurate. It is suppose to show how many used bytes are
   still in the ring buffer, but even when the ring buffer was empty it would
   still show there were bytes used.
 
 - Fix a bug in eventfs where reading a dynamic event directory (open) and then
   creating a dynamic event that goes into that diretory screws up the accounting.
   On close, the newly created event dentry will get a "dput" without ever having
   a "dget" done for it. The fix is to allocate an array on dir open to save what
   dentries were actually "dget" on, and what ones to "dput" on close.

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.
