Subject: [PATCH 1/1] io_uring: remove io_prep_next_work()
Date:   Sat, 29 Feb 2020 22:48:45 +0300
Message-Id: <d5893319c019695321a357cb1f09e76ed40715d1.1583005556.git.asml.silence@gmail.com>

io-wq cares about IO_WQ_WORK_UNBOUND flag only while enqueueing, so
it's useless setting it for a next req of a link. Thus, removed it
from io_prep_linked_timeout(), and inline the function.
