[nf-next,v3,00/14] nf_tables datapath ruleset blob and register tracking

Hi,

The following patchset contains v3 updates for the datapath ruleset
representation and new infrastructure to skip redundant selector store
to register operations [1].

Changes only to patch 7 and 12.

- Patch 7:  Add more memory checks to the routine that builds the blob,
            as requested by Florian.

- Patch 12: Update nft_bitwise reduce routine to deal with different
            source and destination registers.
