*gyah*...  I'd missed the !@#!# macro you've added there.  Could you
explain the reasons for using it at all?  Not to mention anything
else, you've missed
#  define d_refcount(d)                 ((d)->d_count)
in Lustre.  What's the point of your macro (d_refcount -> d_count), anyway?  
All references outside of fs/namei.c, fs/dcache.c, include/linux/dcache.h
should be via d_count(dentry) anyway...
