fstrim on BTRFS
Hi!
With 3.2-rc4 (probably earlier), Ext4 seems to remember what areas it
trimmed:
merkaba:~> fstrim -v /boot
/boot: 224657408 bytes were trimmed
merkaba:~> fstrim -v /boot
/boot: 0 bytes were trimmed
But BTRFS does not:
merkaba:~> fstrim -v /
/: 4431613952 bytes were trimmed
merkaba:~> fstrim -v /
/: 4341846016 bytes were trimmed
Is it planned to add this feature to BTRFS
