-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.
-

-Fixes: 47d68979cc96 ("md/raid0: fix bug with chunksize not a power of 2.")
