i don't think it's the right way.

doesn't it make write(2) and mmap'ed accesses update atime
in somewhat unpredictable manner?

because i don't think the problem can be solved properly without
vnode interface changes, i plan to export nfsd_use_loan as a sysctl knob
for now.  does it make sense for you?

for long term, i think it's better to extend VOP_SETATTR so that
it can be used for this purpose.

(although i think it's silly to rely on atime over nfs...)
