In an ideal userland software world, the counters of the traps would be zero.
But they are not. And without fixup, the mkfs.btrfs fails to run properly, and
creates a broken filesystem that crashes the kernel.

If a broken btrfs filesystem crashes the kernel, you should definitively 
report it as a bug to the btrfs developers.  Filesystem code must be 
immune to any kind of corruptions and gracefully cope with them.
