Name:rim the uncommitted chunks from tree

Proto:static void trim_marked(struct audit_tree *tree)

Type:void

Parameter:

TypeParameterName
struct audit_tree *tree
616  spin_lock( & hash_lock)
617  If goner Then
618  spin_unlock( & hash_lock)
619  Return
622  When p != chunks cycle
623  node = list_entry - get the struct for this entry*@ptr: the &struct list_head pointer.*@type: the type of the struct this is embedded in.*@member: the name of the list_head within the struct.(p, structnode, list)
624  q = next
625  If index; upper bit indicates 'will prune' & 1U << 31 Then
626  list_del_init - deletes entry from list and reinitialize it.*@entry: the element to delete from the list.
627  list_add - add a new entry*@new: new entry to be added*@head: list head to add it after* Insert a new entry after the specified head.* This is good for implementing stacks.
630  spin_unlock( & hash_lock)
632  Remove tree from chunks. If 'tagged' is set, remove tree only from tagged* chunks. The function expects tagged chunks are all at the beginning of the* chunks list.
634  spin_lock( & hash_lock)
635  If Not root && Not goner Then
636  goner = 1
637  spin_unlock( & hash_lock)

639  kill_rules(audit_context(), tree)
640  list_del_init - deletes entry from list and reinitialize it.*@entry: the element to delete from the list.
641  mutex_unlock - release the mutex*@lock: the mutex to be released* Unlock a mutex that has been locked by this task previously.* This function must not be used in interrupt context. Unlocking* of a not locked mutex is not allowed.
