This KCOV extension by Andrey allows syzkaller to collect coverage from background kernel threads e.g. parsing incoming USB packets and unambiguously associate it with one of multiple parallel test processes running. To some degree unique for fuzzing coverage. Moar bugs coming!https://twitter.com/andreyknvl/status/1221784089340121088 …

Good Q. It needs explicit annotations for code regions in kernel threads with some ID that matches ID armed in the test process KCOV. Eg USB code says "here I process request for USB bus 42", test process - "I am working with USB bus 42, gimme that coverage".
