Add a new SUNRPC_CMD_CACHE_FLUSH generic netlink command that allows userspace to flush the sunrpc auth caches (ip_map and unix_gid) without writing to /proc/net/rpc/*/flush. An optional SUNRPC_A_CACHE_FLUSH_MASK u32 attribute selects which caches to flush (bit 1 = ip_map, bit 2 = unix_gid). If the attribute is omitted, all sunrpc caches are flushed. This is used by exportfs to replace its /proc-based cache_flush() with a netlink equivalent, with /proc fallback for older kernels.
