I must confess that I am more inclined to remove this Kconfig option entirely than I am to remove the "Experimental". ;-) > > kernel/rcutree_plugin.h: pr_info("\tExperimental no-CBs CPUs: %s.\n", nocb_buf); > > kernel/rcutree_plugin.h: pr_info("\tExperimental polled no-CBs CPUs.\n"); > > Hehe, that's indeed what I inspired from ;-) I guess we can rerun the earlier "how to mark Kconfig options as not yet being ready for 100 million unsuspecting victims^Wusers. ;-) Then again, I do have the warning at the bottom of the help info, so might be OK removing the "Experimental".
