Sure, and a whole lot of the callsites are ("..._%d", cpu), hence the
unfortune :(

BTW, we could name nfsd threads differently :

Currently, they all are named : "nfsd"

If SVC_POOL_PERCPU is selected, we could name them :
nfsd_c0 -> nfsd_cN

If SVC_POOL_PERNODE is selected, we could name them :
nfsd_n0  -> nfsd_nN

That would help to check with "ps aux" which cpu/nodes are under  
stress.

I like it!

Yup, patch welcomed.--b.

(Annoying fact: some initscripts stop nfsd using a rough equivalent of
"killall nfsd".  So the name of the threads is arguably ABI.  I think
those initscripts are nuts and deserve what they get, but that may be
because I'm forgetting the reason they do that.)
