clang produces a false-positive warning as it fails to notice
that "lost = true" implies that "ret" is initialized:
net/rxrpc/output.c:402:6: error: variable 'ret' is used uninitialized whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]
if (lost)
^~~~
net/rxrpc/output.c:437:6: note: uninitialized use occurs here
if (ret >= 0) {
^~~
net/rxrpc/output.c:402:2: note: remove the 'if' if its condition is always false
if (lost)
^~~~~~~~~
net/rxrpc/output.c:339:9: note: initialize the variable 'ret' to silence this warning
int ret, opt;
^
= 0
Rearrange the code to make that more obvious and avoid the warning.

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.
