Linux Kernel 3.18.8 Arrives with IPv6, IPv4, and EXT4 Improvements

Linux kernel 3.18.8 fixes CPU unplug issues, fixes netxen_nic_poll() logic, now initializes unicast_sock sk_pacing_rate on IPv4, removes the awful unicast_sock on IPv4, repairs a panic in rate estimators, and it now ignores journal checksum on remount on EXT4 file systems.
