Subject: rcutorture: Add a scenario for Tiny SRCU
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=23ca09670312a373d0b72bc7f87bd32323fb673f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

rcutorture: Add a scenario for Tiny SRCU

This commit adds an SRCU-t rcutorture scenario for the new Tiny SRCU
implementation, removing the need to pass the --bootargs parameter to
kvm.sh to run Tiny SRCU tests.  This commit also adds SRCU-t to the set
of scenarios that are run by default.
