Subject: [PATCH 04/16] io_uring: kill io_rw_buffer_select() wrapper
Date: Sun, 1 May 2022 14:56:41 -0600 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>
After the recent changes, this is direct call to io_buffer_select()
anyway. With this change, there are no wrappers left for provided
buffer selection.
