This will cause the next invocation of\nforce_quiescent_state() to end the grace period.\n\nWithout this fix, this hang can be triggered in an hour or so on\nsome machines with rcutorture and random CPU onlining/offlining.\nWith this fix, these same machines pass a full 10 hours of this\nsort of abuse.\n\nSigned-off-by: Paul E.

This new algorithm\u0027s update-side expense\nis similar to that of classic hierarchical RCU, and, in absence\nof read-side preemption or blocking, is exactly that of classic\nhierarchical RCU.  Perhaps more important, this new algorithm\nhas a much simpler implementation, saving well over 1,000 lines\nof code compared to mainline\u0027s implementation of preemptable\nRCU, which will hopefully be retired in favor of this new\nalgorithm.\n\nThe simplifications are obtained by maintaining per-task\nnesting state for running tasks, and using a simple\nlock-protected algorithm to handle accounting when tasks block\nwithin RCU read-side critical sections, making use of lessons\nlearned while creating numerous user-level RCU implementations\nover the past 18 months.\n\nSigned-off-by: Paul E.
