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. --- net/ethtool/bitset.h | 37 +++++++++++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 net/ethtool/bitset.h (limited to 'net/ethtool/bitset.h') diff --git a/net/ethtool/bitset.h b/net/ethtool/bitset.h new file mode 100644 index 000000000..07bc547d4 --- /dev/null +++ b/net/ethtool/bitset.h @@ -0,0 +1,37 @@ +/* SPDX-License-Identifier: GPL-2.0-only */ + +#ifndef _NET_ETHTOOL_BITSET_H +#define _NET_ETHTOOL_BITSET_H + +#include +#include + +#define ETHNL_MAX_BITSET_SIZE S16_MAX + +typedef const char (*const ethnl_string_array_t)[ETH_GSTRING_LEN]; + +int ethnl_bitset_is_compact(const struct nlattr *bitset, bool *compact); +int ethnl_bitset_size(const unsigned long *val, const unsigned long *mask, + unsigned int nbits, ethnl_string_array_t names, + bool compact); +int ethnl_bitset32_size(const u32 *val, const u32 *mask, unsigned int nbits, + ethnl_string_array_t names, bool compact); +int ethnl_put_bitset(struct sk_buff *skb, int attrtype, + const unsigned long *val, const unsigned long *mask, + unsigned int nbits, ethnl_string_array_t names, + bool compact); +int ethnl_put_bitset32(struct sk_buff *skb, int attrtype, const u32 *val, + const u32 *mask, unsigned int nbits, + ethnl_string_array_t names, bool compact); +int ethnl_update_bitset(unsigned long *bitmap, unsigned int nbits, + const struct nlattr *attr, ethnl_string_array_t names, + struct netlink_ext_ack *extack, bool *mod); +int ethnl_update_bitset32(u32 *bitmap, unsigned int nbits, + const struct nlattr *attr, ethnl_string_array_t names, + struct netlink_ext_ack *extack, bool *mod); +int ethnl_parse_bitset(unsigned long *val, unsigned long *mask, + unsigned int nbits, const struct nlattr *attr, + ethnl_string_array_t names, + struct netlink_ext_ack *extack); + +#endif /* _NET_ETHTOOL_BITSET_H */ -- cgit v1.3.1
