Subject: [PATCH 08/14] io_uring: remove __io_state_file_put
Date: Tue, 19 Jan 2021 13:32:41 +0000	[thread overview]
Message-ID: <499e267d7241475afa3ef7e58490a257ee2dcd03.1611062505.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>

The check in io_state_file_put() is optimised pretty well when called
from __io_file_get(). Don't pollute the code with all these variants.
