Digging into the email that provides the cornerstone of Linux kernel

that actually reach the mainline, including tracking the path that
patches take—or don’t take. Three researchers reported on some efforts
they have made on kernel email analysis at the 2019
Embedded Linux Conference Europe (ELCE), held in late October in Lyon, France.
