From: "Maciej S. Szmigiero" <maciej.szmigiero@oracle.com>
btrfs currently prints information about space cache or free space tree being in use on every remount, regardless whether such remount actually enabled or disabled one of these features.
This is actually unnecessary since providing remount options changing the state of these features will explicitly print the appropriate notice.
Let's instead print such unconditional information just on an initial mount to avoid filling the kernel log when, for example, laptop-mode-tools remount the fs on some events.
