Jiri Slaby d19af0a764 kcm: fix /proc memory leak ... Every open of /proc/net/kcm leaks 16 bytes of memory as is reported by kmemleak: unreferenced object 0xffff88059c0e3458 (size 192): comm "cat", pid 1401, jiffies 4294935742 (age 310.720s) hex dump (first 32 bytes): 28 45 71 96 05 88 ff ff 00 10 00 00 00 00 00 00 (Eq............. 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<ffffffff8156a2de>] kmem_cache_alloc_trace+0x16e/0x230 [<ffffffff8162a479>] seq_open+0x79/0x1d0 [<ffffffffa0578510>] kcm_seq_open+0x0/0x30 [kcm] [<ffffffff8162a479>] seq_open+0x79/0x1d0 [<ffffffff8162a8cf>] __seq_open_private+0x2f/0xa0 [<ffffffff81712548>] seq_open_net+0x38/0xa0 ... It is caused by a missing free in the ->release path. So fix it by providing seq_release_net as the ->release method.
