As mentioned in an earlier email thread [1], 4.19.99 broke the ability
to create stateful and stateless device links between the same set of
devices when it pulled in a valid bug fix [2]. While the fix was valid,
it removes a functionality that was present before the bug fix.

This patch series attempts to fix that by pulling in more patches from
upstream. I've just done compilation testing so far. But wanted to send
out a v1 to see if this patch list was acceptable before I fixed up the
commit text format to match what's needed for stable mailing list.

Some of the patches are new functionality, but for a first pass, it was
easier to pull these in than try and fix the conflicts. If these patches
are okay to pull into stable, then all I need to do is fix the commit
text.

Thanks,
Saravana
