This pull request contains the following branches: docs.2022.04.20a: Documentation updates. fixes.2022.04.20a: Miscellaneous fixes. nocb.2022.04.11b: Callback-offloading updates, mainly simplifications. rcu-tasks.2022.04.11b: RCU-tasks updates, including some -rt fixups, handling of systems with sparse CPU numbering, and a fix for a boot-time race-condition failure. srcu.2022.05.03a: Put SRCU on a memory diet in order to reduce the size of the srcu_struct structure. torture.2022.04.11b: Torture-test updates fixing some bugs in tests and closing some testing holes. torture-tasks.2022.04.20a: Torture-test updates for the RCU tasks flavors, most notably ensuring that building rcutorture and friends does not change the RCU-tasks-related Kconfig options. torturescript.2022.04.20a: Torture-test scripting updates. exp.2022.05.11a: Expedited grace-period updates, most notably providing milliseconds-scale (not all that) soft real-time response from synchronize_rcu_expedited(). This is also the first time in almost 30 years of RCU that someone other than me has pushed for a reduction in the RCU CPU stall-warning timeout, in this case by more than three orders of magnitude from 21 seconds to 20 milliseconds. This tighter timeout applies only to expedited grace periods. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEbK7UrM+RBIrCoViJnr8S83LZ+4wFAmKG2zcTHHBhdWxtY2tA a2VybmVsLm9yZwAKCRCevxLzctn7jGXgD/90xtRtZyN0umlN/IOBBn8fIOM+BAMu 5k3ef6wLsXKXlLO13WTjSitypX9LEFwytTeVhEyN4ODeX0cI9mUmts6Z8/6sV92D fN8vqTavveE7m5YfFfLRvDRfVHpB0LpLMM+V0qWPu/F8dWPDKA0225rX9IC7iICP LkxCuNVNzJ0cLaVTvsUWlxMdHcogydXZb1gPDVRhnR6iVFWCBtL4RRpU41CoSNh4 fWRSLQak6OhZRFE7hVoLQhZyLE0GIw1fuUJgj2fCllhgGogDx78FQ8jHdDzMEhVk cD4Yel5vUPiy2AKphGfi28bKFYcyhVBnD/Jq733VJV0/szyddxNbz0xKpEA0/8qh w1T7IjBN6MAKHSh0uUitm6U24VN13m4r30HrUQSpp71VFZkUD4QS6TismKsaRNjR lK4q2QKBprBb3Hv7KPAGYT1Us3aS7qLPrgPf3gzSxL1aY5QV0A5UpPP6RKTLbWPl CEQxEno6g5LTHwKd5QD74dG8ccphg9377lDMJpeesYShBqlLNrNWCxqJoZk2HnSf f2dTQeQWrtRJjeTGy/4cfONCGZTghE0Pch43XMzLLt3ZTuDc8FVM0t3Xs9J5Kg22 zmThQh6LRXTGjrb1vLiOrjPf5JaTnX2Sz8OUJTo/ZxwcixxP/mj8Ja+W81NjfqnK LLZ1D6UN4a8n9A== =4spH -----END PGP SIGNATURE----- Merge tag 'rcu.2022.05.19a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu Pull RCU update from Paul McKenney: - Documentation updates - Miscellaneous fixes - Callback-offloading updates, mainly simplifications - RCU-tasks updates, including some -rt fixups, handling of systems with sparse CPU numbering, and a fix for a boot-time race-condition failure - Put SRCU on a memory diet in order to reduce the size of the srcu_struct structure - Torture-test updates fixing some bugs in tests and closing some testing holes - Torture-test updates for the RCU tasks flavors, most notably ensuring that building rcutorture and friends does not change the RCU-tasks-related Kconfig options - Torture-test scripting updates - Expedited grace-period updates, most notably providing milliseconds-scale (not all that) soft real-time response from synchronize_rcu_expedited().
