Subject: [PATCH] rt: Add documentation describing what kernel debug options to
add for testing
References: SLE Realtime Extension
Patch-mainline: Never, SLERT specific
Stress testing of the kernel may benefit from setting debugging options that
are too expensive to run under production but do not necessarily belong in
rt_debug either.
This documents the *additional* debug options required on top of the parent
SLE debug configuration.
