Detailed Description

struct ttm_base_object

: hash entry for the per-device object hash. : derived type this object is base class for. : Other ttm_object_files can access this object.

: Pointer to ttm_object_file of the creator. NULL if the object was not created by a user request. (kernel object).

: Number of references to this object, not including the hash entry. A reference to a base object can only be held by a ref object.

: A function to be called when there are no more references to this object. This function should destroy the object (or make sure destruction eventually happens), and when it is called, the object has already been taken out of the per-device hash. The parameter "base" should be set to NULL by the function.

: A function to be called when a reference object with another ttm_ref_type than TTM_REF_USAGE is deleted. This function may, for example, release a lock held by a user-space process.

This struct is intended to be used as a base struct for objects that are visible to user-space. It provides a global name, race-safe access and refcounting, minimal access contol and hooks for unref actions.
