Michal Luczaj says: ==================== net: Fix some callers of copy_from_sockptr() Some callers misinterpret copy_from_sockptr()'s return value. The function follows copy_from_user(), i.e. returns 0 for success, or the number of bytes not copied on error. Simply returning the result in a non-zero case isn't usually what was intended. Compile tested with CONFIG_LLC, CONFIG_AF_RXRPC, CONFIG_BT enabled. Last patch probably belongs more to net-next, if any. Here as an RFC.

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.
