[PATCH] knfsd: split svc_serv into pools
Split out the list of idle threads and pending sockets from svc_serv into a new svc_pool structure, and allocate a fixed number (in this patch, 1) of pools per svc_serv. The new structure contains a lock which takes over several of the duties of svc_serv->sv_lock, which is now relegated to protecting only sv_tempsocks, sv_permsocks, and sv_tmpcnt in svc_serv. The point is to move the hottest fields out of svc_serv and into svc_pool, allowing a following patch to arrange for a svc_pool per NUMA node or per CPU. This is a major step towards making the NFS server NUMA-friendly.
