This wakeup ensures that the\nCPU will eventually handle the end of the grace period, including invoking\nits RCU callbacks.\n\nHowever, Pascal Chapperon\u0027s test setup shows that the timer handler\nrcu_idle_gp_timer_func() really does get invoked in some cases. This is\nproblematic because this can cause the CPU that entered dyntick-idle\nmode despite still having RCU callbacks pending to remain in\ndyntick-idle mode indefinitely, which means that its RCU callbacks might\nnever be invoked. This situation can result in grace-period delays or\neven system hangs, which matches Pascal\u0027s observations of slow boot-up\nand shutdown (https://lkml.org/lkml/2012/4/5/142).

The number of srcu_read_unlock() operations\non a given counter is limited to the number of tasks in the system,\nwhich given the Linux kernel\u0027s current structure is limited to far less\nthan 2^30 on 32-bit systems and far less than 2^62 on 64-bit systems.\n(Something about a limited number of bytes in the kernel\u0027s address space.)\n\nTherefore, if srcu_read_lock() increments the upper bits, then\nsrcu_read_unlock() need not do so. In this case, an srcu_read_lock() and\nan srcu_read_unlock() will flip the lower bit of the upper field of the\ncounter.

But because RCU readers do not exclude\nupdaters, a list might become empty between the time that list_empty()\nclaimed it was non-empty and the time that list_first_entry_rcu() is\ninvoked. Therefore, the list_empty() test cannot be separated from the\nlist_first_entry_rcu() call. This commit therefore combines these to\nmacros to create a new list_first_or_null_rcu() macro that replaces\nthe old (and unsafe) list_first_entry_rcu() macro.\n\nThis patch incorporates Paul\u0027s review comments on the previous version of\nthis patch available here:\n\nhttps://lkml.org/lkml/2012/4/2/536\n\nThis patch cannot break any upstream code because list_first_entry_rcu()\nis not being used anywhere in the kernel (tested with grep(1)), and any\nexternal code using it is probably broken as a result of using it.\n\nSigned-off-by: Michel Machado \u003cmichel@digirati.com.br\u003e\nCC: \"Paul E.
