The patch series fix the bug of writing raid sysfs.

Changes in v2:
 - in patch 1, move check out of md_bitmap_checkpage().
 - in patch 2, use div64_u64() and DIV64_U64_ROUND_UP() instead of directly
   '/', and chang old_delay/old_delay to unsigned int.
 - in patch 4, use 'goto' to make changes more readable.

Changes in v2:
 - add patch "md/raid10: optimize check_decay_read_errors()".
 - in patch 2, return ret-value of strict_strtoul_scaled if error occurs.
 - in patch 3, optimize format.

Li Nan (4):
  md/raid10: fix slab-out-of-bounds in md_bitmap_get_counter
  md/raid10: fix overflow in safe_delay_store
  md/raid10: fix wrong setting of max_corr_read_errors
  md/raid10: optimize check_decay_read_errors()

Btw, what does "OLK-5.10" mean?
