From 5b234d1539c26b011a6a68fc583080a75fa02efb Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Fri, 29 Jan 2016 11:07:02 +0000 Subject: bitbake: utils: Add ability to change the process name Being able to tell the bitbake processes apart is useful for debugging. Add a helper function which allows this without making it a hard dependency. Errors are ignored, this is just nice to have.
