I believe the FS-Cache code wasn't removed from the RHEL 5.x kernels -
it was just the fsc option that was disabled in the kernel mount options
and also disabled in nfs-utils (mount.nfs) as well.
It would be quite easy to remove this kernel patch and rebuild a kernel
(and rebuild nfs-utils, or use a version of mount.nfs from 5.2)-
however, the FS-Cache code in these kernels is now quite old and very
likely to be buggy - RedHat has not updated the kernel code to match the
mainline kernels since 5.2
Personally, I would wait for CentOS 6 - but even then, FS-Cache is
currently classed as a 'preview' technology in the RHEL 6.0 beta

Thanks for the informative post; I was a bit puzzled at first after reading the previous postings regarding this topic as I have seen the FS-Cache: Loaded message every time I log in as a user whose home directory has been automounted.
