Back in December was the proposal to finally enable FSTRIM by default for Fedora 32 in benefiting solid-state storage. Today the formal approval was given by the Fedora Engineering and Steering Committee to go ahead with this long overdue change.
The change is to enable the systemd fstrim.timer unit by default for running FSTRIM weekly on EXT4/XFS/Btrfs/F2FS file-systems running on flash-based storage devices. FSTRIM is used for notifying the underlying storage devices about unused blocks for wear leveling and more efficient handling.
