but important race-condition bugs.
torture.2021.09.13b: Other torture-test updates, most notably
better checking of module parameters. In addition, rcutorture
may now be run on CONFIG_PREEMPT_RT kernels.

specifying the new CONFIG_KCSAN_STRICT kconfig option rather
than maintaining an ever-changing list of individual KCSAN
kconfig options.
