I don't know if you can apply it to a partition. For example, /dev/sda3. The man page does not inform me.
Apparently mkfs.ext4, with discard enabled will scarify the inodes when the filesystem is created. www.systutorials.com/docs/linux/man/8-mkfs.ext4/ I'm still not sure about weekly trims. That wasn't enabled by systemd by default. I had to do systemctl enable fstrim.timer in order to create the targets. Only got to that last week. I'm kind of a slow ship turning on this build.
