From d98af5f4552058a5c22030641ef79cee92c61f54 Mon Sep 17 00:00:00 2001 From: Daeho Jeong Date: Tue, 15 Mar 2022 21:14:14 -0700 Subject: f2fs: introduce gc_urgent_mid mode We need a mid level of gc urgent mode to do GC forcibly in a period of given gc_urgent_sleep_time, but not like using greedy GC approach and switching to SSR mode such as gc urgent high mode. This can be used for more aggressive periodic storage clean up.
