Song Liu says:

====================

Changes v4 => v5:
1. Clean up and style change in 2/2. (Andrii)

Changes v3 => v4:
1. Move mmap_unlock_work to task_iter.c to fix build for .config without
   !CONFIG_PERF_EVENTS. (kernel test robot <lkp@intel.com>)

Changes v2 => v3:
1. Avoid using x86 only function in selftests. (Yonghong)
2. Add struct file and struct vm_area_struct to btf_task_struct_ids, and
   use it in bpf_find_vma and stackmap.c. (Yonghong)
3. Fix inaccurate comments. (Yonghong)

Changes v1 => v2:
1. Share irq_work with stackmap.c. (Daniel)
2. Add tests for illegal writes to task/vma from the callback function.
   (Daniel)
3. Other small fixes.

Add helper bpf_find_vma. This can be used in some profiling use cases. It
might also be useful for LSM.

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.
