====================
This set adds probe_read_{user,kernel}(), probe_read_str_{user,kernel}()
helpers, fixes probe_write_user() helper and selftests. For details please
see individual patches.
Thanks!
v2 -> v3:
- noticed two more things that are fixed in here:
- bpf uapi helper description used 'int size' for *_str helpers, now u32
- we need TASK_SIZE_MAX + guard page on x86-64 in patch 2 otherwise
we'll trigger the 00c42373d3 warn as well, so full range covered now
v1 -> v2:
- standardize unsafe_ptr terminology in uapi header comment (Andrii)
- probe_read_{user,kernel}[_str] naming scheme (Andrii)
- use global data in last test case, remove relaxed_maps (Andrii)
- add strict non-pagefault kernel read funcs to avoid warning in
kernel probe read helpers (Alexei)

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.
