From 3001ca77128273cc5634d79f5306ce2e5a14ec41 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Thu, 16 Aug 2007 13:31:27 +0200 Subject: New function blk_req_append_bio ll_back_merge_fn is currently exported to SCSI where is it used, together with blk_rq_bio_prep, in exactly the same way these functions are used in __blk_rq_map_user. So move the common code into a new function (blk_rq_append_bio), and don't export ll_back_merge_fn any longer.
