Look at nfsrv_fhtovp(), it shows how we decompose file handles. Assuming=20
its callers aren't being tricky, you should have the contents of a=20
fhandle_t.

Our file handle have two components. The first is a file system ID, which=
=20
identifies the mount point parrenting the vnode. The remainder is a=20
file-system-specific tag that identifies the vnode within the fs. For ffs,=
=20
it is a combination of the inode # and the inode's generation #.

Take care,

Bill
