gen_pool_alloc_algo_owner	gen_pool_alloc_algo_owner - allocate special memory from the pool@pool: pool to allocate from@size: number of bytes to allocate from the pool@algo: algorithm passed from caller@data: data passed to algorithm*@owner: optionally retrieve the chunk owner
gen_pool_avail	获得内存池的可用空间
check_mm
get_work_pwq
get_work_pool	get_work_pool - return the worker_pool a given work was associated with@work: the work item of interest Pools are created and destroyed under wq_pool_mutex, and allows read* access under RCU read lock. As such, this function should be
get_work_pool_id	get_work_pool_id - return the worker pool ID a given work is associated with@work: the work item of interest Return: The worker_pool ID @work was last associated with.* %WORK_OFFQ_POOL_NONE if none.
work_is_canceling
calc_global_load	alc_load - update the avenrun load estimates 10 ticks after the* CPUs have updated calc_load_tasks.* Called from the global timer code.
__mutex_owner	Internal helper function; C doesn't allow us to hide it :/* DO NOT USE (outside of mutex code).
__mutex_trylock_or_owner	Trylock variant that retuns the owning task on failure.
__mutex_handoff	Give up ownership to a specific task, when @task = NULL, this is equivalent* to a regular unlock. Sets PICKUP on a handoff, clears HANDOF, preserves* WAITERS. Provides RELEASE semantics like a regular unlock, the
ww_mutex_set_context_fastpath	After acquiring lock with fastpath, where we do not hold wait_lock, set ctx* and wake up any waiters so they can recheck.
__mutex_unlock_slowpath
rwsem_test_oflags	Test the flags in the owner field.
__rwsem_set_reader_owned	The task_struct pointer of the last owning reader will be left in* the owner field.* Note that the owner value just indicates the task has owned the rwsem* previously, it may not be the real owner or one of the real owners
rwsem_set_nonspinnable	Set the RWSEM_NONSPINNABLE bits if the RWSEM_READER_OWNED flag* remains set. Otherwise, the operation will be aborted.
rwsem_owner	Return just the real task structure pointer of the owner
rwsem_owner_flags	Return the real task structure pointer of the owner and the embedded* flags in the owner. pflags must be non-NULL.
rwsem_mark_wake	handle the lock release when processes blocked on it that can now run* - if we come here from up_xxxx(), then the RWSEM_FLAG_WAITERS bit must* have been set
rwsem_try_write_lock	This function must be called with the sem->wait_lock held to prevent* race conditions between checking the rwsem wait list and setting the* If wstate is WRITER_HANDOFF, it will make sure that either the handoff
rwsem_down_read_slowpath	Wait for the read lock to be granted
rwsem_down_write_slowpath	Wait until we successfully acquire the write lock
rcu_torture_stats_print	Print torture statistics
free_event	Used to free events which have a known refcount of 1, such as in error paths* where the event isn't exposed yet and inherited events.
perf_mmap
do_shrink_slab
node_page_state	Determine the per node value of a stat item.
workingset_eviction	workingset_eviction - note the eviction of a page from memory@target_memcg: the cgroup that is causing the reclaim@page: the page being evicted* Returns a shadow entry to be stored in @page->mapping->i_pages in place
workingset_refault	workingset_refault - evaluate the refault of a previously evicted page@page: the freshly allocated replacement page@shadow: shadow entry of the evicted page* Calculates and evaluates the refault distance of the previously* evicted page in the context of
vmalloc_nr_pages
__purge_vmap_area_lazy	Purges all lazily-freed vmap areas.
get_swap_pages
si_swapinfo
hugetlb_report_usage
clear_hwpoisoned_pages
propagate_protected_usage
page_counter_set_max	page_counter_set_max - set the maximum number of pages allowed@counter: counter@nr_pages: limit to set* Returns 0 on success, -EBUSY if the current number of pages on the* counter already exceeds the specified limit.
page_counter_set_min	page_counter_set_min - set the amount of protected memory@counter: counter@nr_pages: value to set* The caller must serialize invocations on the same counter.
page_counter_set_low	page_counter_set_low - set the amount of protected memory@counter: counter@nr_pages: value to set* The caller must serialize invocations on the same counter.
memcg_events
mem_cgroup_oom_control_read
__memory_events_show
mem_cgroup_protected	mem_cgroup_protected - check if memory consumption is in the normal range@root: the top ancestor of the sub-tree being checked@memcg: the memory cgroup to check* WARNING: This function is not stateless! It can only be used as part
swap_events_show
zs_get_total_pages
get_io_context	get_io_context - increment reference count to io_context@ioc: io_context to get Increment reference count to @ioc.
put_io_context	put_io_context - put a reference of io_context@ioc: io_context to put Decrement reference count of @ioc and release it if the count reaches* zero.
ima_show_htable_value
__destroy_inode
sb_prepare_remount_readonly
__ns_get_path
fsnotify_unmount_inodes	snotify_unmount_inodes - an sb is unmounting. handle any watched inodes.@sb: superblock being unmounted. Called during unmount with no locks held, so needs to be safe against* concurrent modifiers. We temporarily drop sb->s_inode_list_lock and CAN block.
ep_insert	Must be called with "mtx" held.
io_account_mem
rwsem_is_locked	In all implementations count != 0 means locked
zone_managed_pages
percpu_ref_is_zero	判断percpu无计数引用

global_numa_state
zone_numa_state_snapshot
global_zone_page_state
global_node_page_state
zone_page_state
zone_page_state_snapshot	More accurate version that also considers the currently pending* deltas. For that we need to loop over all cpus to find the current* deltas. There is no synchronization so the result cannot be* exactly accurate either.
get_mm_counter	per-process(per-mm_struct) statistics.
mm_pgtables_bytes
frag_mem_limit	Memory Tracking Functions.
page_counter_read
memcg_page_state	dx can be of type enum memcg_stat_item or node_stat_item.* Keep in sync with memcg_exact_page_state().
