Linear makes no sense for distributing IO's among many devices. Linear
is a concatenation.
If the real-world application involves parallel access to lots of
different files, then XFS on a linear concatenation /will/ make sense,
if your allocation groups match your concatenated devices. It won't
give you faster access to any of the files, but it will let you have
fast access to several files at the same time. Of course, YMMV
according to the setup and application.
