From cd36d7a17f9da68be9aa67185ba3ad7969934a19 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Wed, 31 Jan 2018 09:30:34 +0800 Subject: f2fs: fix to clear CP_TRIMMED_FLAG Once CP_TRIMMED_FLAG is set, after a reboot, we will never issue discard before LBA becomes invalid again, fix it by clearing the flag in checkpoint without CP_TRIMMED reason.
