+Subject: [PATCH] md/raid0: fix restore to sector variable in
+ raid0_make_request
+
+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.")
