Subject: [PATCH 2/3] io_uring: rename io_file_put()
Date: Sun, 17 May 2020 14:13:41 +0300 [thread overview]
Message-ID: <b9125175eb3c0e218e4d56958df09fa0220c691c.1589713554.git.asml.silence@gmail.com> (raw)
In-Reply-To: <cover.1589713554.git.asml.silence@gmail.com>
io_file_put() deals with flushing state's file refs, adding "state" to
its name makes it a bit clearer. Also, avoid double check of
state->file in __io_file_get() in some cases.
