函数名称:Wait for a grace period to elapse. But it is illegal to invoke* synchronize_rcu() from within an RCU read-side critical section.* Therefore, any legal call to synchronize_rcu() is a quiescent
函数原型:void synchronize_rcu(void)
返回类型:void
参数:无
121 | RCU_LOCKDEP_WARN(lock_is_held( & rcu_bh_lock_map) || lock_is_held( & rcu_lock_map) || lock_is_held( & rcu_sched_lock_map), "Illegal synchronize_rcu() in RCU read-side critical section") |

crc_t10dif_rehash | |
sugov_stop | |
sync_runqueues_membarrier_state | |
SYSCALL_DEFINE2 | sys_membarrier - issue memory barriers on a set of threads*@cmd: Takes command values defined in enum membarrier_cmd |
psi_trigger_destroy | |
lockdep_free_key_range_reg | Used in module |
lockdep_unregister_key | Unregister a dynamically allocated key. |
kmsg_dump_unregister | kmsg_dump_unregister - unregister a kmsg dumper.*@dumper: pointer to the kmsg_dumper structure* Removes a dump device from the system. Returns zero on success and* %-EINVAL otherwise. |
rcu_test_sync_prims | Test each non-SRCU synchronous grace-period wait API. This is* useful just after a change in mode for these primitives, and* during early boot. |
rcu_sync_enter | _sync_enter() - Force readers onto slowpath*@rsp: Pointer to rcu_sync structure to use for synchronization* This function is used by updaters who need readers to make use of* a slowpath during the update |
cond_synchronize_rcu | d_synchronize_rcu - Conditionally wait for an RCU grace period*@oldstate: return value from earlier call to get_state_synchronize_rcu()* If a full RCU grace period has elapsed since the earlier call to* get_state_synchronize_rcu(), just return |
free_module | Free a module, remove from lists, etc. |
do_free_init | |
do_init_module | This is where the real work happens.* Keep it uninlined to provide a reliable breakpoint target, e.g. for the gdb* helper command 'lx-symbols'. |
load_module | Allocate and load the module: note that size of section 0 is alwayszero, and we rely on this for optional sections. |
collect_one_slot | Return 1 if all garbages are collected, otherwise 0. |
collect_garbage_slots | |
register_aggr_kprobe | This is the second or subsequent kprobe at the address - handle* the intricacies |
register_kprobe | |
unregister_kprobes | |
ring_buffer_resize | g_buffer_resize - resize the ring buffer*@buffer: the buffer to resize.*@size: the new size.*@cpu_id: the cpu buffer to resize* Minimum size is 2 * BUF_PAGE_SIZE.* Returns 0 on success and < 0 on failure. |
ring_buffer_read_prepare_sync | g_buffer_read_prepare_sync - Synchronize a set of prepare calls* All previously invoked ring_buffer_read_prepare calls to prepare* iterators will be synchronized. Afterwards, read_buffer_read_start* calls on those iterators are allowed. |
ring_buffer_reset_cpu | g_buffer_reset_cpu - reset a ring buffer per CPU buffer*@buffer: The ring buffer to reset a per cpu buffer of*@cpu: The CPU buffer to be reset |
tracing_reset_cpu | |
tracing_reset_online_cpus | |
trace_buffered_event_disable | race_buffered_event_disable - disable buffering events* When a filter is removed, it is faster to not use the buffered* events, and to commit directly into the ring buffer. Free up* the temp buffers when there are no more users. This requires |
trace_probe_remove_file | |
clear_ftrace_pids | |
ftrace_pid_write | |
maybe_wait_bpf_programs | |

smk_list_swap_rcu | smk_list_swap_rcu - swap public list with a private one in RCU-safe way* The caller must hold appropriate mutex to prevent concurrent modifications* to the public list |

unregister_filesystem | register_filesystem - unregister a file system*@fs: filesystem to unregister* Remove a file system that was previously successfully registered* with the kernel |
kern_unmount | |
