Wei Yongjun 476181cb05 dccp: missing destroy of percpu counter variable while unload module ... percpu counter dccp_orphan_count is init in dccp_init() by percpu_counter_init() while dccp module is loaded, but the destroy of it is missing while dccp module is unloaded. We can get the kernel WARNING about this. Reproduct by the following commands: $ modprobe dccp $ rmmod dccp $ modprobe dccp WARNING: at lib/list_debug.c:26 __list_add+0x27/0x5c() Hardware name: VMware Virtual Platform list_add corruption. next->prev should be prev (c080c0c4), but was (null).
