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. --- fs/fuse/args.h | 65 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 65 insertions(+) create mode 100644 fs/fuse/args.h (limited to 'fs/fuse/args.h') diff --git a/fs/fuse/args.h b/fs/fuse/args.h new file mode 100644 index 000000000..ecfe51a19 --- /dev/null +++ b/fs/fuse/args.h @@ -0,0 +1,65 @@ +/* SPDX-License-Identifier: GPL-2.0 */ + +#ifndef _FS_FUSE_ARGS_H +#define _FS_FUSE_ARGS_H + +#include + +struct fuse_mount; + +/** One input argument of a request */ +struct fuse_in_arg { + unsigned size; + const void *value; +}; + +/** One output argument of a request */ +struct fuse_arg { + unsigned size; + void *value; +}; + +struct fuse_args { + u64 nodeid; + u32 opcode; + u32 uid; + u32 gid; + u32 pid; + u8 in_numargs; + u8 out_numargs; + u8 ext_idx; + bool force:1; + bool noreply:1; + bool nocreds:1; + bool in_pages:1; + bool out_pages:1; + bool user_pages:1; + bool out_argvar:1; + bool page_zeroing:1; + bool page_replace:1; + bool may_block:1; + bool is_ext:1; + bool is_pinned:1; + bool invalidate_vmap:1; + bool abort_on_kill:1; + struct fuse_in_arg in_args[4]; + struct fuse_arg out_args[2]; + void (*end)(struct fuse_args *args, int error); + /* Used for kvec iter backed by vmalloc address */ + void *vmap_base; +}; + +/** FUSE folio descriptor */ +struct fuse_folio_desc { + unsigned int length; + unsigned int offset; +}; + +struct fuse_args_pages { + struct fuse_args args; + struct folio **folios; + struct fuse_folio_desc *descs; + unsigned int num_folios; +}; + +#endif /* _FS_FUSE_ARGS_H */ -- cgit v1.3.1
