- Stack usage reduction for probe events:
- Allocate string buffers from the heap for uprobe, eprobe, kprobe,
and fprobe events to avoid stack overflow.
- Allocate traceprobe_parse_context from the heap to prevent
potential stack overflow.
- Fix a typo in the above commit.
- New features for eprobe and tprobe events:
- Add support for arrays in eprobes.
- Support multiple tprobes on the same tracepoint.
- Improve efficiency:
- Register fprobe-events only when it is enabled to reduce overhead.
- Register tracepoints for tprobe events only when enabled to
resolve a lock dependency.
- Code Cleanup:
- Add kerneldoc for traceprobe_parse_event_name() and __get_insn_slot().
- Sort #include alphabetically in the probes code.
- Remove the unused 'mod' field from the tprobe-event.
- Clean up the entry-arg storing code in probe-events.
- Selftest update
- Enable fprobe events before checking enable_functions in selftests.

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 reStructuredText 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.
