However it do report another possible leak :) debian-mips:~# cat /sys/kernel/debug/kmemleak unreferenced object 0x8f085000 (size 4096): comm "swapper", pid 1, jiffies 4294937670 (age 1043.280s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<801ac7a8>] __kmalloc+0x130/0x180 [<80532500>] flow_cache_cpu_prepare+0x50/0xa8 [<8052378c>] flow_cache_init_global+0x90/0x138 [<80100584>] do_one_initcall+0x174/0x1e0 [<8050c348>] kernel_init+0xe4/0x174 [<80103d4c>] kernel_thread_helper+0x10/0x18 debian-mips:~# > So, I guess everything is fine regarding udp_init_table.
