[PATCH 0/3] Cleanup scan_swap_map_slots() a little

From: Wei Yang

Function scan_swap_map_slots() is used to iterate swap_map[] array for an
available swap entry. While after several optimizations, e.g. for ssd case,
the logic of this function is a little not easy to catch.

This patch set tries to clean up the logic a little:

* shows the ssd/non-ssd case is handled mutually exclusively
* remove some unnecessary goto for ssd case

Wei Yang (3):
mm/swapfile.c: offset is only used when there is more slots
mm/swapfile.c: explicitly show ssd/non-ssd is handled mutually
exclusive
mm/swapfile.c: remove the unnecessary goto for SSD case
