Subject: f2fs: fix to clear CP_TRIMMED_FLAG
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d4fff1411d4ee644f924e5a8f605db587c87ed90;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

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.

Fixes: 1f43e2ad7bff ("f2fs: introduce CP_TRIMMED_FLAG to avoid unneeded discard")
