Subject: [RFC PATCH v4 2/3] net: Make `move_addr_to_user()` be a non static function
Date: Fri,  7 Jan 2022 07:00:04 +0700
Message-ID: <20220107000006.1194026-3-ammarfaizi2@gnuweeb.org>

In order to add recvfrom support for io_uring, we need to call
`move_addr_to_user()` from fs/io_uring.c.

This makes `move_addr_to_user()` be a non static function so we can
call it from io_uring.
