 That's likely.  Guaranteed rate I/O (GRIO) works only with XFS
 filesystems (this is true on IRIX) and not on Linux.

 Just to clarify: Someone asked why the XFS patch is so large.  I just
 said the XFS patch also includes some GRIO stuff.  I didn't mean to say
 that the feature is implemented on Linux (in fact, it's not, if you use
 the corresponding ioctl it will return ENOSYS).  Remember that XFS is
 not Linux specific, and it'd be a nightmare to maintain two completely
 different source trees, one for Linux and one for IRIX.
