Remember, only in Workstation.
how about discards for the things that fstrim doesn't get? Two
main things
I know of:
- swap: Do discard at swapon time by setting "discard=once" in
/etc/fstab would be somewhat similar to the periodic fstrim call. I
don't know how much impact the "discard=pages" option might have (the
man page says it is asynchronous, but it might make low-memory
situations worse).
- logical volumes: Set "issue_discards = 1" in /etc/lvm/lvm.conf so that
removed LVs get discarded.
Are you asking for these just in Workstation, or are you suggesting that this
is something all of Fedora adopts?
