I think Lachlan had good answers to your questions... I'm curious, are
you using xfs_ncheck on a mounted filesystem for any particular reason?
It seems that maybe if you are concerned about the out-of-date info on
a mounted filesystem, maybe you are attempting to use this from a script
or something as part of a larger tool, and that may not be a good idea
in general. xfs_ncheck, a wrapper around xfs_db, reads the block device
directly, and nothing in the kernel guarantees consistency between the
block device address space and the filesystem address space.
