Subject: libcephfs invalidate upcalls

Hi John,

I prototyped an invalidate upcall for libcephfs and the Gasesha Ceph fsal, building on the Client invalidation callback registrations.

As you suggested, NFS (or AFS, or DCE) minimally expect a more generic "cached vnode may have changed" trigger than the current inode and dentry invalidates, so I extended the model slightly to hook cap revocation, feedback appreciated.

git@github.com:linuxbox2/ceph.git , branch invalidate
git@github.com:linuxbox2/nfs-ganesha.git , branch ceph-invalidates

thanks,

Matt
