2008-03-28drivers/net/arcnet/arcnet.c: use time_* macrosS.Caglar Onur
The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values. So use the time_after() macro, defined in linux/jiffies.h, which deals with wrapping correctly.

2008-03-28[SOCK]: Introduce a percpu inuse counters array (v2).Pavel Emelyanov
And redirect sock_prot_inuse_add and _get to use one. As far as the dereferences are concerned. Before the patch we made 1 dereference to proto->inuse.add call, the call itself and then called the __get_cpu_var() on a static variable. After the patch we make a direct call, then one dereference to proto->inuse_idx and then the same __get_cpu_var() on a still static variable. So this patch doesn't seem to produce performance penalty on SMP. This is not per-net yet, but I will deliberately make NET_NS=y case separated from NET_NS=n one, since it'll cost us one-or-two more dereferences to get the struct net and the inuse counter.

The inuse counters are going to become a per-cpu array. Introduce an index for this array on the struct proto. To handle the case of proto register-unregister-register loop the bitmap is used. All its bits manipulations are protected with proto_list_lock and a sanity check for the bitmap being exhausted is also added.

Instead we must use local_irq_{save,restore}().
