This is the first in a series from an ongoing review of the RCU documentation. "Why are people thinking -that- about RCU? Oh. Because that is an entirely reasonable interpretation of its documentation." fixes.2022.08.31b: Miscellaneous fixes. kvfree.2022.08.31b: Improved memory allocation and heuristics. nocb.2022.09.01a: Improve rcu_nocbs diagnostic output. poll.2022.08.31b: Add full-sized polled RCU grace period state values. These are the same size as an rcu_head structure, which is double that of the traditional unsigned long state values that may still be obtained from et_state_synchronize_rcu(). The added size avoids missing overlapping grace periods. This benefit is that call_rcu() can be replaced by polling, which can be attractive in situations where RCU-protected data is aged out of memory. Early in the series, the size of this state value is three unsigned longs. Later in the series, the synchronize_rcu() and synchronize_rcu_expedited() fastpaths are reworked to permit the full state to be represented by only two unsigned longs. This reworking slows these two functions down in SMP kernels running either on single-CPU systems or on systems with all but one CPU offlined, but this should not be a significant problem. And if it somehow becomes a problem in some yet-as-unforeseen situations, three-value state values can be provided for only those situations. Finally, a pair of functions named same_state_synchronize_rcu() and same_state_synchronize_rcu_full() allow grace-period state values to be compared for equality. This permits users to maintain lists of data structures having the same state value, removing the need for per-data-structure grace-period state values, thus decreasing memory footprint. poll-srcu.2022.08.31b: Polled SRCU grace-period updates, including adding tests to rcutorture and reducing the incidence of Tiny SRCU grace-period-state counter wrap. tasks.2022.08.31b: Improve Tasks RCU diagnostics and quiescent-state detection. ---------------------------------------------------------------- Joel Fernandes (Google) (1): rcu/kfree: Fix kfree_rcu_shrink_count() return value Michal Hocko (1): rcu: Back off upon fill_page_cache_func() allocation failure Paul E.

Thanx, Paul ------------------------------------------------------------------------ tag rcu.2023.06.22a Tagger: Paul E. McKenney Date: Thu Jun 22 14:01:35 2023 -0700 RCU pull request for v6.5 This pull contains the following branches: doc.2023.05.10a: Documentation updates fixes.2023.05.11a: Miscellaneous fixes, perhaps most notably: o Remove RCU_NONIDLE(). The new visibility of most of the idle loop to RCU has obsoleted this API. o Make the RCU_SOFTIRQ callback-invocation time limit also apply to the rcuc kthreads that invoke callbacks for CONFIG_PREEMPT_RT. o Add a jiffies-based callback-invocation time limit to handle long-running callbacks. (The local_clock() function is only invoked once per 32 callbacks due to its high overhead.) o Stop rcu_tasks_invoke_cbs() from using never-onlined CPUs, which fixes a bug that can occur on systems with non-contiguous CPU numbering. kvfree.2023.05.10a: kvfree_rcu updates o Eliminate the single-argument variant of k[v]free_rcu() now that all uses have been converted to k[v]free_rcu_mightsleep(). o Add WARN_ON_ONCE() checks for k[v]free_rcu*() freeing callbacks too soon. Yes, this is closing the barn door after the horse has escaped, but Murphy says that there will be more horses. nocb.2023.05.11a: Callback-offloading updates o Fix a number of bugs involving the shrinker and lazy callbacks. rcu-tasks.2023.05.10a: Tasks RCU updates torture.2023.05.15a: Torture-test updates rcu-urgent.2023.06.06a: Urgent SRCU fix (already pulled) -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEbK7UrM+RBIrCoViJnr8S83LZ+4wFAmSUuukTHHBhdWxtY2tA a2VybmVsLm9yZwAKCRCevxLzctn7jLB5EACWArBYSbXh9kx6RP3LRkOd//fQWuqx z/RmHjMx3a2uIQpsbeAj+jrgHYzSOi7Afdnx2s0gUIWGjpF4d+e31eco9xTQtWIs A3/pXUlcTyaPXEZh5ro763UyBF/K003TAdo7EZAScTfDNp2knqGdEOyXTOXiAULX GH922kIqg0chbYaWocLY3g5mXeEm+kGY8GrDAB7/B3jHgoyylXzmSULDP4GQV7hw DkM0GOlc3TSzHonnNS6j1xboqY4HhWIDkBrD4Oh5P//ttMpb1b6gs1zEyjCQcNBe a6fnNF+0dUwANIZKroPn/L1uTGsEUhmLFkVK+XIuAit97yWI6t+aRH6TzHHYmkpu wVmLxv/FbJohP7ArWaI8l0gNl0vkli3ZgQXnRvSpCqIFR93AWVMeZsDTGOcLUdry AZEnuGXHnc9UB0KGOIras0o/EQezKq57JUV2bBZjl/GIDc3qiaJKnBhHysPc1iuE UfP052vCaoZxO3U/FrObQhjLZnstKBYHj8WolxMjIyNMlRIvDro6O1WG4+mjeLDP xdrjKGstsJh80CYDei+vJBXsbszhxv8yV4hCQX9JcDl3RjEqOOxgKUnAaP2mm02O MX33P3MZvSsHGoxkJpXDSlkQlbNqDBMIjZXbZLRF4o8fPhVmQU/4QlJN0iFOoXaQ 1qqGrerEzfn0Jw== =3LCd -----END PGP SIGNATURE----- commit 2e31da752c6d0e892f2a9232e18da816d04ee691 Merge: e1bd2334f165 401b0de3ae4f 6b706e5603c4 fbde57d2d299 edff5e9a99e0 ce2544b2d05e de29a96accea Author: Paul E.
