* 'master' of master.kernel.org:/pub/scm/linux/kernel/git/davem/net-2.6: [IRDA] IRNET: Fix build when TCGETS2 is defined. [NET]: docbook fixes for netif_ functions [NET]: Hide the net_ns kmem cache [NET]: Mark the setup_net as __net_init [NET]: Hide the dead code in the net_namespace.c [NET]: Relax the reference counting of init_net_ns [NETNS]: Make the init/exit hooks checks outside the loop [NET]: Forget the zero_it argument of sk_alloc() [NET]: Remove bogus zero_it argument from sk_alloc [NET]: Make the sk_clone() lighter [NET]: Move some core sock setup into sk_prot_alloc [NET]: Auto-zero the allocated sock object [NET]: Cleanup the allocation/freeing of the sock object [NET]: Move the get_net() from sock_copy() [NET]: Move the sock_copy() from the header [TCP]: Another TAGBITS -> SACKED_ACKED|LOST conversion [TCP]: Process DSACKs that reside within a SACK block
