38  * object range.
44  * an object requires specific handling.
90  * which include stack traces to the user of the object, the original allocation
96  * Allocate a KFENCE object. Allocators must not call this function directly,
102  * kfence_alloc() - allocate a KFENCE object with a low probability
103  * @s:     struct kmem_cache with object requirements
104  * @size:  exact size of the object to allocate (can be less than @s->size
110  * * non-NULL - pointer to a KFENCE object.
132  * kfence_ksize() - get actual amount of memory allocated for a KFENCE object
133  * @addr: pointer to a heap object
136  * * 0     - not a KFENCE object, must call __ksize() instead,
139  * kfence_ksize() returns the number of bytes requested for a KFENCE object at
140  * allocation time. This number may be less than the object size of the
146  * kfence_object_start() - find the beginning of a KFENCE object
147  * @addr: address within a KFENCE-allocated object
149  * Return: address of the beginning of the object.
152  * easy to calculate the beginning of an object given a pointer inside it and
153  * the object size. The same is not true for KFENCE, which places a single
154  * object at either end of the page. This helper function is used to find the
155  * beginning of a KFENCE-allocated object.
160  * __kfence_free() - release a KFENCE heap object to KFENCE pool
161  * @addr: object to be freed
165  * Release a KFENCE object and mark it as freed.
170  * kfence_free() - try to release an arbitrary heap object to KFENCE pool
171  * @addr: object to be freed
174  * * false - object doesn't belong to KFENCE pool and was ignored,
175  * * true  - object was released to KFENCE pool.
177  * Release a KFENCE object and mark it as freed. May be called on any object,
180  * determine if it was a KFENCE object or not.
212  * @object: the object
215  * * false - not a KFENCE object
