+From a81157768a00e8cf8a7b43b5ea5cac931262374f Mon Sep 17 00:00:00 2001
+From: Eric Work <work.eric@gmail.com>
+Date: Mon, 18 May 2015 23:26:23 -0700
+Subject: [PATCH] md/raid0: fix restore to sector variable in
+ raid0_make_request
+
+The variable "sector" in "raid0_make_request()" was improperly updated
+by a call to "sector_div()" which modifies its first argument in place.
+Commit 47d68979cc968535cb87f3e5f2e6a3533ea48fbd restored this variable
+after the call for later re-use. Unfortunetly the restore was done after
+the referenced variable "bio" was advanced. This lead to the original
+value and the restored value being different. Here we move this line to
+the proper place.
+
+One observed side effect of this bug was discarding a file though
+unlinking would cause an unrelated file's contents to be discarded.
+
+Signed-off-by: NeilBrown <neilb@suse.de>
+Fixes: 47d68979cc96 ("md/raid0: fix bug with chunksize not a power of 2.")
+Cc: stable@vger.kernel.org (any that received above backport)
