Jesper Dangaard Brouer 6d7b857d54 net: use lib/percpu_counter API for fragmentation mem accounting ... Replace the per network namespace shared atomic "mem" accounting variable, in the fragmentation code, with a lib/percpu_counter. Getting percpu_counter to scale to the fragmentation code usage requires some tweaks. At first view, percpu_counter looks superfast, but it does not scale on multi-CPU/NUMA machines, because the default batch size is too small, for frag code usage. Thus, I have adjusted the batch size by using __percpu_counter_add() directly, instead of percpu_counter_sub() and percpu_counter_add(). The batch size is increased to 130.000, based on the largest 64K fragment memory usage. This does introduce some imprecise memory accounting, but its does not need to be strict for this use-case. It is also essential, that the percpu_counter, does not share cacheline with other writers, to make this scale. Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: David S.
