====================
Netfilter fixes for net:

The following patchset contains Netfilter fixes for net:

1. Fix spurious -EEXIST error from userspace due to
   padding holes, this was broken since 4.9 days
   when 'ignore duplicate entries on insert' feature was
   added.

2. Fix a sched-while-atomic bug, present since 5.19.

3. Properly remove elements if they lack an "end range".
   nft userspace always sets an end range attribute, even
   when its the same as the start, but the abi doesn't
   have such a restriction. Always broken since it was
   added in 5.6, all three from myself.

4 + 5: Bound chain needs to be skipped in netns release
   and on rule flush paths, from Pablo Neira.
