mount.cifs: document the 'fsc' mount option
Changes since last post:
- added the information about the kernel CONFIG option
- also added the information that caching is currently enabled for files opened as read-only
Document the newly added local caching feature using FS-Cache. This patch
could be queued and considered once the local caching patches gets merged
upstream.
