TECH PREVIEW: fscache may not be fully supported.
Please review provided documentation for limitations.
FS-Cache: Loaded
FS-Cache: Netfs 'nfs' registered for caching

Excerpt from RHEL 6.1 Technical Notes, Chapter 3. Technology Previews:

FS-Cache
FS-Cache is a new feature in Red Hat Enterprise Linux 6 that enables networked file systems (e.g. NFS) to have a persistent cache of data on the client machine.

… and nothing about the limitations or how to disable fscache.

Tried to add install fscache /bin/true to /etc/modprobe.d/fscache.conf with the following dmesg result (of course, no NFS filesystems mounted):

nfs: Unknown symbol __fscache_read_or_alloc_pages
nfs: Unknown symbol __fscache_relinquish_cookie
nfs: Unknown symbol __fscache_unregister_netfs
nfs: Unknown symbol __fscache_maybe_release_page
