Re: [PATCH] xfs_repair doesn't detect corrupt btree roots in nodes

Looks ok to me.

Can you test if it works by manually corrupting some B+Tree using xfs_db 
(or in fact, you can write a small program which does so. You can just 
write a program which reads the location on the disk directly, modify 
the 512 size sector corresponding to these with some selected fields and 
write them out.)

Try the code when major B+Trees are corrupted --> AGI /BCNTi/BSIZE tree.
