**调用者**
名称	描述
__key_instantiate_and_link	Instantiate a key and link it into the target keyring atomically. Must be* called with the target keyring's semaphore writelocked. The target key's* semaphore need not be locked as instantiation is serialised by* key_construction_mutex.
key_reject_and_link	key_reject_and_link - Negatively instantiate a key and link it into the keyring.@key: The key to instantiate.@timeout: The timeout on the negative key.*@error: The error to return when the key is hit.
evict	Free the inode passed in, removing it from the lists it is still connected* to
unlock_new_inode	lock_new_inode - clear the I_NEW state and wake up any waiters@inode: new inode to unlock Called when the inode is fully initialised to clear the new state of the* inode and wake up anyone waiting for the inode to finish initialisation.
discard_new_inode
inode_sync_complete
unlock_buffer
bd_clear_claiming
task_clear_jobctl_trapping	ask_clear_jobctl_trapping - clear jobctl trapping bit@task: target task If JOBCTL_TRAPPING is set, a ptracer is waiting for us to enter TRACED.* Clear it and wake up the ptracer. Note that we don't need any further* locking
key_garbage_collector	Reaper for unused keys.
d_instantiate_new	This should be equivalent to d_instantiate() + unlock_new_inode(),* with lockdep-related part of unlock_new_inode() done before* anything else. Use that instead of open-coding d_instantiate()/* unlock_new_inode() combinations.
