Well with xfs there is no fsck, but there is xfs_repair which is
the equivalent. You can also run xfs_check which will not fix a
filesystem but runs an extensive set of checks on its consistency.

Andrea the interfaces between xfs and the kernel are about to change,
we will no longer require code in vmscan.c and the code in buffer.c
gets simpler.

I was not aware that the xfs code in the aa kernels still
predated 1.1, in that case upgrading is definitely a good idea.
