True. We have knobs to cope with filesystems whose st_dev or
st_ctime are not stable, but there is no such knob to tweak for
st_ino. Shouldn't be too hard to add such, though. One approach is
to do something like the attached patch, and declare, define,
initialize, and set trust_inum in a way similar to how we handle
trust_ctime in the existing code.
