Name:If the object has been wiped upon free, make sure it's fully initialized by* zeroing out freelist pointer.
Proto:static __always_inline void maybe_wipe_obj_freeptr(struct kmem_cache *s, void *obj)
Type:void
Parameter:
| Type | Parameter | Name |
|---|---|---|
| struct kmem_cache * | s | |
| void * | obj |
| 2661 | If Value for the false possibility is greater at compile time(slab_want_init_on_free(s)) && obj Then memset((void * )((char * )obj + Free pointer offset ), 0, size of * ) |
| Name | Describe |
|---|---|
| slab_alloc_node | Inlined fastpath so that allocation functions (kmalloc, kmem_cache_alloc)* have the fastpath folded into their functions. So no function call* overhead for requests that can be satisfied on the fastpath. |
| kmem_cache_alloc_bulk | Note that interrupts must be enabled when calling this function. |
