Ok, do you rmmod the xfs.ko module and insert new ones, or just
reboot whenever you have a new module for testing? I'm assuming that
you are unloading and reloading based on the "[last unloaded: xfs]"
above. That has always made me nervous about memory corruption
intorudced by a previous module affecting the running of a current
module....

Cheers,

Dave.
