====================
Netfilter/IPVS updates for net-next
The following pull request contains Netfilter/IPVS updates for net-next
containing 90 patches from Eric Biederman.
The main goal of this batch is to avoid recurrent lookups for the netns
pointer, that happens over and over again in our Netfilter/IPVS code. The idea
consists of passing netns pointer from the hook state to the relevant functions
and objects where this may be needed.
You can find more information on the IPVS updates from Simon Horman's commit
merge message:
c3456026adc0 ("Merge tag 'ipvs2-for-v4.4' of https://git.kernel.org/pub/scm/linux/kernel/git/horms/ipvs-next").
Exceptionally, this time, I'm not posting the patches again on netdev, Eric
already Cc'ed this mailing list in the original submission. If you need me to
make, just let me know.
====================
