3.16.36-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Sebastian Ott <sebott@xxxxxxxxxxxxxxxxxx>
commit b707c65ae70e24c47a0ce4a7279224ce8f0ffb7f upstream.
When we refuse a non REQ_TYPE_FS request in the build request function
we already hold the queue lock. Thus we must not call blk_end_request_all
but __blk_end_request_all.
Reported-by: Peter Oberparleiter <oberpar@xxxxxxxxxxxxxxxxxx>
Fixes: de9587a ('s390/scm_blk: fix endless loop for requests != REQ_TYPE_FS')
