[ Upstream commitcb57908653] This code is supposed to pass negative "err" values for tracing but it passes positive values instead. The problem is that the trace_svcsock_tcp_send() function takes a long but "err" is an int and "sent" is a u32. The negative is first type promoted to u32 so it becomes a high positive then it is promoted to long and it stays positive. Fix this by casting "err" directly to long.

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.
