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. --- include/rdma/mr_pool.h | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) create mode 100644 include/rdma/mr_pool.h (limited to 'include/rdma/mr_pool.h') diff --git a/include/rdma/mr_pool.h b/include/rdma/mr_pool.h new file mode 100644 index 000000000..e77123bcb --- /dev/null +++ b/include/rdma/mr_pool.h @@ -0,0 +1,17 @@ +/* SPDX-License-Identifier: GPL-2.0-only */ +/* + * Copyright (c) 2016 HGST, a Western Digital Company. + */ +#ifndef _RDMA_MR_POOL_H +#define _RDMA_MR_POOL_H 1 + +#include + +struct ib_mr *ib_mr_pool_get(struct ib_qp *qp, struct list_head *list); +void ib_mr_pool_put(struct ib_qp *qp, struct list_head *list, struct ib_mr *mr); + +int ib_mr_pool_init(struct ib_qp *qp, struct list_head *list, int nr, + enum ib_mr_type type, u32 max_num_sg, u32 max_num_meta_sg); +void ib_mr_pool_destroy(struct ib_qp *qp, struct list_head *list); + +#endif /* _RDMA_MR_POOL_H */ -- cgit v1.3.1
