3  * I/O Address Space ID allocator. There is one global IOASID space, split into
22  * about an allocator. There are two types of allocators:
24  * - Default allocator always has its own XArray to track the IOASIDs allocated.
29  * 1. Default allocator is always available, not dynamically registered. This is
32  * 2. Custom allocators take precedence over the default allocator.
38  * 5. When switching between custom allocator and default allocator, all IOASIDs
39  *    must be freed to ensure unadulterated space for the new allocator.
41  * @ops:	allocator helper functions and its data
44  * @flags:	attributes of the allocator
46  * @rcu:	used for kfree_rcu when unregistering allocator
97 /* Allocate and initialize a new custom allocator with its helper functions */
123  * ioasid_register_allocator - register a custom allocator
124  * @ops: the custom allocator ops to be registered
