From 9cc63f8bcd560c760d0b12e15bba8f81c86237cf Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Fri, 14 Aug 2026 15:43:51 -0700 Subject: Merge branches 'expcb.2026.07.24a', 'misc.2026.07.30a', 'rcu-tasks.2026.07.30a', 'srcu.2026.08.11a' and 'torture.2026.08.14a' into HEAD Changes: Make expedited grace periods expedite normal RCU callbacks Miscellaneous fixes: * Improve diagnostic output with character task states. * Mark accesses to inform KCSAN of concurrency design. * Move from kmalloc() to kmalloc_obj(). * Documentation updates. * Improve handling of RCU deferred quiescent states. * Clean up unused function arguments and structure fields. * Reduce show_rcu_gp_kthreads() stack space. Tasks RCU updates: * Clean up after SRCU re-implementation of Tasks Trace RCU. * Mark accesses to inform KCSAN of concurrency design. * Add ->lazy_timer status to diagnostic output. * Remove an unnecessary memory barrier. * Fix a data race, courtesy of KCSAN. * Documentation updates. * Convert cond_resched_tasks_rcu_qs() from macro to static inline function. SRCU updates: * Add Rust helpers for SRCU. * Avoid losing queued work at cleanup_srcu_struct() time. Torture-test updates: * Preparation work for immediate RCU priority deboosting. * Test RCU readers from real interrupt handlers (as opposed to softirq). * Simplify code through use of cpumask_next_wrap(). * Improve diagnostic output with character task states. * Add rcutorture.nwriters parameter to allow lightweight stall testing, and rcutorture.stall_only to make doing so easier. * Test an RCU Tasks Trace grace period implying an RCU grace period. * Make RCU Tasks Trace torturing track reader batches. * Fix a data race, courtesy of KCSAN. * Plug a shuffle_tmp_mask memory leak on kthread spawn failure. --- usr/dummy-include/endian.h | 0 usr/dummy-include/limits.h | 8 ++++++++ usr/dummy-include/netinet/if_ether.h | 0 usr/dummy-include/netinet/in.h | 0 usr/dummy-include/stddef.h | 13 +++++++++++++ usr/dummy-include/stdint.h | 17 +++++++++++++++++ usr/dummy-include/string.h | 12 ++++++++++++ usr/dummy-include/sys/ioctl.h | 0 usr/dummy-include/sys/socket.h | 12 ++++++++++++ usr/dummy-include/sys/time.h | 3 +++ usr/dummy-include/sys/types.h | 0 usr/dummy-include/time.h | 0 usr/dummy-include/unistd.h | 0 13 files changed, 65 insertions(+) create mode 100644 usr/dummy-include/endian.h create mode 100644 usr/dummy-include/limits.h create mode 100644 usr/dummy-include/netinet/if_ether.h create mode 100644 usr/dummy-include/netinet/in.h create mode 100644 usr/dummy-include/stddef.h create mode 100644 usr/dummy-include/stdint.h create mode 100644 usr/dummy-include/string.h create mode 100644 usr/dummy-include/sys/ioctl.h create mode 100644 usr/dummy-include/sys/socket.h create mode 100644 usr/dummy-include/sys/time.h create mode 100644 usr/dummy-include/sys/types.h create mode 100644 usr/dummy-include/time.h create mode 100644 usr/dummy-include/unistd.h (limited to 'usr/dummy-include') diff --git a/usr/dummy-include/endian.h b/usr/dummy-include/endian.h new file mode 100644 index 000000000..e69de29bb diff --git a/usr/dummy-include/limits.h b/usr/dummy-include/limits.h new file mode 100644 index 000000000..49b17c10c --- /dev/null +++ b/usr/dummy-include/limits.h @@ -0,0 +1,8 @@ +/* SPDX-License-Identifier: GPL-2.0-only */ +#ifndef _DUMMY_LIMITS_H +#define _DUMMY_LIMITS_H + +#define INT_MAX ((int)(~0U >> 1)) +#define INT_MIN (-INT_MAX - 1) + +#endif /* _DUMMY_LIMITS_H */ diff --git a/usr/dummy-include/netinet/if_ether.h b/usr/dummy-include/netinet/if_ether.h new file mode 100644 index 000000000..e69de29bb diff --git a/usr/dummy-include/netinet/in.h b/usr/dummy-include/netinet/in.h new file mode 100644 index 000000000..e69de29bb diff --git a/usr/dummy-include/stddef.h b/usr/dummy-include/stddef.h new file mode 100644 index 000000000..525489daf --- /dev/null +++ b/usr/dummy-include/stddef.h @@ -0,0 +1,13 @@ +/* SPDX-License-Identifier: GPL-2.0-only */ +#ifndef _DUMMY_STDDEF_H +#define _DUMMY_STDDEF_H + +#define offsetof(TYPE, MEMBER) __builtin_offsetof(TYPE, MEMBER) + +#ifdef __cplusplus +#define NULL 0 +#else +#define NULL ((void *)0) +#endif + +#endif /* _DUMMY_STDDEF_H */ diff --git a/usr/dummy-include/stdint.h b/usr/dummy-include/stdint.h new file mode 100644 index 000000000..93b1962fd --- /dev/null +++ b/usr/dummy-include/stdint.h @@ -0,0 +1,17 @@ +/* SPDX-License-Identifier: GPL-2.0-only */ +#ifndef _DUMMY_STDINT_H +#define _DUMMY_STDINT_H + +#include + +typedef __u64 uint64_t;
