mainline inclusion
from mainline-5.9-rc1
commit f063c547
category: feature
bugzilla: https://bugzilla.openeuler.org/show_bug.cgi?id=27
CVE: NA
---------------------------

Whoever called io_prep_linked_timeout() should also do
io_queue_linked_timeout(). __io_queue_sqe() doesn't follow that for the
punting path leaving linked timeouts prepared but never queued.

Fixes: 6df1db6b ("io_uring: fix mis-refcounting linked timeouts")
