Description :
When using xfsrestore to restore a dump to a non-xfs filesystem,
it issues the following warnings:

 xfsrestore: NOTE: attempt to reserve 46720 bytes for
 /home/sky/xfsrestorehousekeepingdir/dirattr using F_ALLOCSP64 failed:
 Inappropriate ioctl for device (25)

 xfsrestore: NOTE: attempt to reserve 45496 bytes for
 /home/sky/xfsrestorehousekeepingdir/namreg using F_ALLOCSP64 failed:

As far as I can tell, the restore continues without a problem.

These warnings should be silenced as they are unecessarily
scary, and xfsrestore should ideally work on non-xfs filesystems
(with reduced functionality).
