Analyze and fix the following issue in the Linux kernel code: torture: Make torture.sh refscale testing qualify verbose_batched
Problem Details: In torture.sh, the testing of refscale incorrectly used verbose_batched as a kernel boot parameter, which causes this parameter to be passed to the init process. This commit therefore prefixes it with refscale, so that refscale.verbose_batched is passed to the kernel. Signed-off-by: Paul E. McKenney ...
