Andrew/Tyler/Dustin,
This get_nlinks parameter was never used by the only mainline user,
ecryptfs; and it has never been used by unionfs or wrapfs either. I've been
using this patch in unionfs for over 4 years now; given that it's a no-op to
ecryptfs, I think it can safely go straight to mainline.
BTW, Mike Halcrow signed off on this patch a long time ago.
