Subject: [PATCH 0/3] Cleanup scan_swap_map_slots() a little
Date: Sat, 28 Mar 2020 06:05:17 +0000 [thread overview]
Message-ID: <20200328060520.31449-1-richard.weiyang@gmail.com> (raw)
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
