From 93aaa5e99475e9450d55c1b32f08199e533a3f65 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Thu, 29 Apr 2021 18:23:51 +0100 Subject: bitbake: runqueue: Handle deferred task rehashing in multiconfig builds If the hash of a task changes and that hash is a deferred task (e.g. a multiconfig build), we need to ensure that the hash change propagates through to all the tasks else the build will run multiple copies of the task, sometimes with oddly differing results as the outhashes of native tasks built in differing locations can confuse things.
