btrfs_mark_used_tree_blocks skips the reloc roots for some reason, which

Any idea on why it's skipped in the first place?

Yeah I added it apparently in

439ce45e ("Btrfs-progs: add --init-extent-tree to btrfsck")

because at the time we didn't deal with the reloc tree properly and I was trying
to unfuck a users file system.  I'm going to say that isn't the case anymore.
Thanks,
