What’s the proper way of raising “feature request” to include btrfs support in kernel for Rock5 provided by radxa? Preferably trackable way. Looks like “Issues” are disabled in kernel’s GitHub repo.
Btrfs support in kernel
Armbian has it enabled by defult.
… but since this hardware is not using mainstream kernel, I suggest you to be careful with using BTRFS. tl;dr; don’t use it until mainline kernel support emerges.
