From 0e5e81114de1c4ac32e36f057256653a04f27a33 Mon Sep 17 00:00:00 2001 From: Daeho Jeong Date: Thu, 2 Jul 2020 13:14:14 +0900 Subject: f2fs: add GC_URGENT_LOW mode in gc_urgent Added a new gc_urgent mode, GC_URGENT_LOW, in which mode F2FS will lower the bar of checking idle in order to process outstanding discard commands and GC a little bit aggressively.
