Subject: io_uring: don't adjust LINK_HEAD in cancel ltimeout
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ac877d2edd094e161801d72b49cfb56c5fc860fb;p=linux.git

io_uring: don't adjust LINK_HEAD in cancel ltimeout

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.
