It was only added to the main btrfs maintainer's tree about a day ago. As far as I understand the bug, it only happens if you have the bootloader installed in the root partition (not a separate /boot) and you run an fstrim on the whole partition (fstrim /) either manually or from a system script or such. I suppose it would possibly happen if you have the bootloader installed in a btrfs /boot partition and ran fstrim on that too. However, Fedora doesn't support booting from a btrfs filesystem at the moment and typical installs create a separate /boot partition that is ext4. I may have some details wrong and would gladly be corrected if so. We'll pick up the fix once it lands in Linus' tree. Until then, the safety is mostly determine by that of btrfs in general.
