Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next
Pablo Neira Ayuso says: ==================== The following patchset contains fixes for recently applied Netfilter/IPVS updates to the net-next tree, most relevantly they are: * Fix sparse warnings introduced in the RCU conversion, from Julian Anastasov. * Fix wrong endianness in the size field of IPVS sync messages, from Simon Horman. * Fix missing if checking in nf_xfrm_me_harder, from Dan Carpenter. * Fix off by one access in the IPVS SCTP tracking code, again from Dan Carpenter. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
