Pull `lTracing fixes for 6.1-rc3: - Fixed NULL pointer dereference in the ring buffer wait-waiters code for machines that have less CPUs than what nr_cpu_ids returns. The buffer array is of size nr_cpu_ids, but only the online CPUs get initialized. - Fixed use after free call in ftrace_shutdown. - Fix accounting of if a kprobe is enabled - Fix NULL pointer dereference on error path of fprobe rethook_alloc(). - Fix unregistering of fprobe_kprobe_handler - Fix memory leak in kprobe test module * tag 'trace-v6.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: kprobe: Fix memory leak in test_gen_kprobe/kretprobe_cmd() tracing/fprobe: Fix to check whether fprobe is registered correctly fprobe: Check rethook_alloc() return in rethook initialization kprobe: reverse kp->flags when arm_kprobe failed ftrace: Fix use-after-free for dynamic ftrace_ops ring-buffer: Check for NULL cpu_buffer in ring_buffer_wake_waiters()
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.
