[OE-core] Changing external kernel module results in rebuild of whole kernel

[Mike Looijmans]

Something in recent OE-core triggered a weird dependency "backfire".

If I change a recipe for a kernel module (a bb recipe that does "inherit 
module") this will trigger a rebuild of the whole kernel.

This turns the 5-second job of just updating a single module into a several 
minute workout for the build machine, and then causes boards to re-write the 
kernel into flash needlessly when upgrading.

I now see this on all projects using OE-core master. I can't really pin what 
caused it though. Anyone else seen this?


Kind regards,
