mainline inclusion
from mainline-5.5-rc1
commit 978db57e
category: feature
bugzilla: https://bugzilla.openeuler.org/show_bug.cgi?id=27
CVE: NA
---------------------------

If we don't use the normal completion path, we may skip killing links
that should be errored and freed. Add __io_double_put_req() for use
within the completion path itself, other calls should just use
io_double_put_req().
