====================
tcp: mmap: rework zerocopy receive
syzbot reported a lockdep issue caused by tcp mmap() support.
I implemented Andy Lutomirski nice suggestions to resolve the
issue and increase scalability as well.
First patch is adding a new getsockopt() operation and changes mmap()
behavior.
Second patch changes tcp_mmap reference program.
v4: tcp mmap() support depends on CONFIG_MMU, as kbuild bot told us.
v3: change TCP_ZEROCOPY_RECEIVE to be a getsockopt() option
instead of setsockopt(), feedback from Ka-Cheon Poon
v2: Added a missing page align of zc->length in tcp_zerocopy_receive()
Properly clear zc->recv_skip_hint in case user request was completed.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
