Hi Chao, Could you add this state in print_cp_state() of f2fs-tools as well? Thanks, On 04/27, Chao Yu wrote: > Introduce CP_TRIMMED_FLAG to indicate all invalid block were trimmed > before umount, so once we do mount with image which contain the flag, > we don't record invalid blocks as undisca

[PATCH 2/2] f2fs: introduce CP_TRIMMED_FLAG to avoid unneeded discard

Introduce CP_TRIMMED_FLAG to indicate all invalid block were trimmed before umount, so once we do mount with image which contain the flag, we don't record invalid blocks as undiscard one, when fstrim is being triggered, we can avoid issuing redundant discard commands. Signed-off-by: Chao Yu ---
