There is a type bug because the return statement:
return ret < 0 ? ret : recv_cnt;
The issue is that ret is an int, recv_cnt is a u32 and the function
returns ssize_t, which is a signed long. The way that the type promotion
works is that the negative error codes are first cast to u32 and then
to signed long. The error codes end up being positive instead of
negative and the callers treat them as success.

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 reStructuredText 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.
