  32 Subject: md/raid0: fix restore to sector variable in raid0_make_request
  33
  34 The variable "sector" in "raid0_make_request()" was improperly updated
  35 by a call to "sector_div()" which modifies its first argument in place.
  36 Commit 47d68979cc968535cb87f3e5f2e6a3533ea48fbd restored this variable
  37 after the call for later re-use.  Unfortunetly the restore was done after
  38 the referenced variable "bio" was advanced.  This lead to the original
  39 value and the restored value being different.  Here we move this line to
  40 the proper place.
  41
  42 One observed side effect of this bug was discarding a file though
  43 unlinking would cause an unrelated file's contents to be discarded.
