Name:slob_page_alloc() - Allocate a slob block within a given slob_page sp.*@sp: Page to look in.*@size: Size of the allocation.*@align: Allocation alignment.*@align_offset: Offset in the allocated block that will be aligned.
Proto:static void *slob_page_alloc(struct page *sp, size_t size, int align, int align_offset, bool *page_removed_from_list)
Type:void
Parameter:
Type | Parameter | Name |
---|---|---|
struct page * | sp | |
size_t | size | |
int | align | |
int | align_offset | |
bool * | page_removed_from_list |
241 | delta = 0 , units = SLOB_UNITS(size) |
243 | * page_removed_from_list = false |
244 | cycle |
254 | If align Then |
255 | aligned = @a is a power of 2 value ((unsignedlong)cur + align_offset, align) - align_offset |
263 | If delta Then |
276 | Else first free object = next |
278 | Else |
281 | Else first free object = cur + units |
287 | If Not SLOB Then |
