Subject: [RFC PATCH v1 2/3] net: Make `move_addr_to_user()` be a non static function
Date: Thu, 30 Dec 2021 08:35:42 +0700	[thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>

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

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