Pull tracing fixes from Steven Rostedt:
"This includes three fixes:
- Fix a deadlock from a previous fix to keep module loading and
function tracing text modifications from stepping on each other
(this has a few patches to help document the issue in comments)
- Fix a crash when the snapshot buffer gets out of sync with the main
ring buffer
- Fix a memory leak when reading the memory logs"
* tag 'trace-v5.2-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
ftrace/x86: Anotate text_mutex split between ftrace_arch_code_modify_post_process() and ftrace_arch_code_modify_prepare()
tracing/snapshot: Resize spare buffer if size changed
tracing: Fix memory leak in tracing_err_log_open()
ftrace/x86: Add a comment to why we take text_mutex in ftrace_arch_code_modify_prepare()
ftrace/x86: Remove possible deadlock between register_kprobe() and ftrace_run_update_code()
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.
