I will post v2 after that one gets accepted. thanks.

It's time to set all these fields to 0 and only initialize those non-zero fields, in case we will add more fields in the future.
[PATCH net] net: sched: set xt_tgchk_param par.nft_compat with false in ipt_init_target
Commit 55917a21d0cc ("netfilter: x_tables: add context to know if extension runs from nft_compat") introduced a member nft_compat to xt_tgchk_param structure. But it didn't set it's value for ipt_init_target. With unexpected value in par.nft_compat, it may return unexpected result in some target's checkentry. This patch is to set par.nft_compat with false in ipt_init_target.
