"fstrim" initially requests discard of all unused blocks, so a large number. But why should it do the same on subsequent calls while it still knows what it did the last time? ext4 caches the information if a particular block group was trimmed, but this information is not persistent. (Using bit EXT4_GROUP_INFO_WAS_TRIMMED_BIT in ext4_group_info.bb_state.) Bastian -- Live long and prosper. -- Spock, "Amok Time", stardate 3372.7
