[Unionfs] Can't mount NFS-exported union anymore in unionfs-1.4

Thank you.

$ grep max mes* | cut -f-2,7- -d' ' | sort | uniq
messages.debug_patch.kernelnfsroot:Nov 30 max 6, conn 1type 1, max 2
messages.debug_patch.mount:Nov 30 max 14, conn 1type 1, max 2
messages.debug_patch.mount:Nov 30 max 14, conn 1type 2, max 4

In kernelnfsroot log, the passed argument 'max' is 6. It is too small to
store the unionfs file handle and unionfs returns an error.
I don't know why nfsd uses such small value in your case, but I will try
reading nfsd source code next week.
