I always want more fuzz for btrfs, so overall this is pretty good.
But there are some comments related to free s

When implemented and enabled, this should circumvent all redundant
checksum verification in filesystem code. However, setting of checksums
is not affected.
The aim is to aid fuzzing efforts which randomly mutate disk images and
so invalidate checksums. Checksum verificatio

Fuzzing is a proven technique to discover exploitable bugs in the Linux
kernel. But fuzzing filesystems is tricky: highly structured disk images
use redundant checksums to verify data integrity. Therefore,
randomly-mutated images are quickly rejected as corrupt, testing only
ping, it seems this had been forgotten.
