[OE-core] questions on patching

[Ola Redell]

Hi all,

I am a bit new to sending in patches to a list like this and 
specifically to OE-core, so I need a bit of guidance.

I have a fix for a bug I found in Jethro in the kernel.bbclass and I 
have tested my fix there (update-alternatives needs a full path also 
when removing an alternative). Now, the bug is around in many different 
branches (laverne, krogoth and master for sure) but that particular 
patch will only apply to Jethro.

I can make a patch for master but would have problems testing it 
thoroughly there without spending quite a bit of time (which I don't 
have at the moment).

Easy questions:
How should I proceed?
How do I know what branches are actively maintained and for which 
patches are welcome?

I should have asked these questions before sending my earlier patch for 
the kernel-module-split.bbclass since this holds for that too.

Thanks,
Ola
