Subject: [PATCH 2/4] io_uring: dont adjust LINK_HEAD in cancel ltimeout
Date: Thu, 22 Oct 2020 16:43:09 +0100 [thread overview]
Message-ID: <eb5aa148a3d6318fd5d876d346ad167d664ec4bf.1603381140.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
An armed linked timeout can never be a head of a link, so we don't need
to clear REQ_F_LINK_HEAD for it.
