Wei Wang f5a5589c72 tcp: use a smaller percpu_counter batch size for sk_alloc ... Currently, a percpu_counter with the default batch size (2*nr_cpus) is used to record the total # of active sockets per protocol. This means sk_sockets_allocated_read_positive() could be off by +/-2*(nr_cpus^2). This under/over-estimation could lead to wrong memory suppression conditions in __sk_raise_mem_allocated(). Fix this by using a more reasonable fixed batch size of 16. See related commit cf86a086a1 ("net/dst: use a smaller percpu_counter batch for dst entries accounting") that addresses a similar issue.
