In this commit the XSKMAP entry lookup function used by the XDP redirect code is moved from the xskmap.c file to the xdp_sock.h header, so the lookup can be inlined from, e.g., the bpf_xdp_redirect_map() function. Further the __xsk_map_redirect() and __xsk_map_flush() is moved to the xsk.c, which lets the compiler inline the xsk_rcv() and xsk_flush() functions. Finally, all the XDP socket functions were moved from linux/bpf.h to net/xdp_sock.h, where most of the XDP sockets functions are anyway. This yields a ~2% performance boost for the xdpsock "rx_drop" scenario.

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.
