The NFS "nosharecache" patch in F7 is broken

[Chuck Ebbert]

If people try mounting several exports from the same filesystem, it fails
with confusing error messages if the mount options are different for some
of the mount points. Adding "nosharecache" to the mount options fixes that,
but people with working setups suddenly find they need this new option to
use a setup that used to work without it. Should we just revert that patch?
