try_to_grab_pendingry_to_grab_pending - steal work item from worklist and disable irq*@work: work item to steal*@is_dwork: @work is a delayed_work*@flags: place to store irq state* Try to grab PENDING bit of @work. This function can handle @work in any
queue_work_onqueue_work_on - queue work on specific cpu*@cpu: CPU number to execute work on*@wq: workqueue to use*@work: work to queue* We queue the work to a specific CPU, the caller must ensure it* can't go away.
queue_work_nodequeue_work_node - queue work on a "random" cpu for a given NUMA node*@node: NUMA node that we are targeting the work for*@wq: workqueue to use*@work: work to queue* We queue the work to a "random" CPU within a given NUMA node
queue_delayed_work_onqueue_delayed_work_on - queue work on specific CPU after delay*@cpu: CPU number to execute work on*@wq: workqueue to use*@dwork: work to queue*@delay: number of jiffies to wait before queueing
queue_rcu_workqueue_rcu_work - queue work after a RCU grace period*@wq: workqueue to use*@rwork: work to queue* Return: %false if @rwork was already pending, %true otherwise

drain_all_stockDrains all per-CPU charge caches for given root_memcg resp. subtree* of the hierarchy under it.
z3fold_freez3fold_free() - frees the allocation associated with the given handle*@pool: pool in which the allocation resided*@handle: handle associated with the allocation returned by z3fold_alloc()* In the case that the z3fold page in which the allocation resides
z3fold_reclaim_pagez3fold_reclaim_page() - evicts allocations from a pool page and frees it*@pool: pool from which a page will attempt to be evicted*@retries: number of pages on the LRU list for which eviction will* be attempted before failing* z3fold reclaim is different
blk_queue_flag_test_and_setlk_queue_flag_test_and_set - atomically test and set a queue flag*@flag: flag to be set*@q: request queue* Returns the previous value of @flag - 0 if the flag was not set and 1 if* the flag was already set.
__blk_mq_tag_busyIf a previously inactive queue goes active, bump the active user count.* We need to do this before try to allocate driver tag, then even if fail* to get tag when first time, the other shared-tag users could reserve* budget for it.

key_revokekey_revoke - Revoke a key
key_invalidatekey_invalidate - Invalidate a key.*@key: The key to be invalidated.* Mark a key as being invalidated and have it cleaned up immediately. The key* is ignored by all searches and other operations from this point.

ima_open_policyma_open_policy: sequentialize access to the policy file
evm_set_keyvm_set_key() - set EVM HMAC key from the kernel*@key: pointer to a buffer with the key data*@size: length of the key data* This function allows setting the EVM HMAC key from the kernel* without using the "encrypted" key subsystem keys
