Refactor: svc_recvfrom() is going to be converted to read into bio_vecs in a moment. Unhook the only other caller, svc_tcp_recv_record(), which just wants to read the 4-byte stream record marker into a kvec. While we're in the area, streamline this helper by straight-lining the hot path, replace dprintk call sites with tracepoints, and reduce the number of atomic bit operations in this path.

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.
