Good point.  I should have said "... the integration of these
next-generation journalling file systems with recent Linux kernels
is somewhat experimental".  I'm sure the underlying architecture of
both of these file systems is quite sound and well tested, but as
one can see from perusing the SGI site, the Linux kernel and IRIX
are different enough to change some of the assumptions on which XFS
is based.  I assume the same is true for OS/2 and Linux .

While I am sure that both the SGI and IBM teams do world-class work,
I wonder how much testing these file systems get relative to ext2/3 ,
especially with fedora-tweaked kernels.  Hence my question.  The same
question holds for reiserfs, of course.  In what circumstances do
these file systems break?
