Subject: [PATCH 3/3] io_uring: simplify io_sqd_update_thread_idle()
Date: Wed, 10 Mar 2021 13:13:55 +0000	[thread overview]
Message-ID: <6982cecd8d4d1493894dbe41f774651891020528.1615381765.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>

Use a more comprehensible() max instead of hand coding it with ifs in
io_sqd_update_thread_idle().
