Subject[PATCH v3 1/7] vmlinux.lds.h: add linker section for KUnit test suites
From
Add a linker section where KUnit can put references to its test suites.
This patch is the first step in transitioning to dispatching all KUnit
tests from a centralized executor rather than having each as its own
separate late_initcall.
