Subject: xprtrdma: use complete() instead complete_all()
From: Daniel Wagner <daniel.wagner@xxxxxxxxxxxx>
commit 5690a22d8612e1788b48b4ea53c59868589cd2db upstream.
There is only one waiter for the completion, therefore there
is no need to use complete_all(). Let's make that clear by
using complete() instead of complete_all().
The usage pattern of the completion is:
waiter context waker context
frwr_op_unmap_sync()
reinit_completion()
ib_post_send()
wait_for_completion()
frwr_wc_localinv_wake()
complete()
