Name:zs_unmap_object
Proto:void zs_unmap_object(struct zs_pool *pool, unsigned long handle)
Type:void
Parameter:
Type | Parameter | Name |
---|---|---|
struct zs_pool * | pool | |
unsigned long | handle |
1362 | obj = handle_to_obj(handle) |
1364 | zspage = get_zspage(page) |
1365 | get_zspage_mapping(zspage, & class_idx, & fg) |
1366 | class = size_class[class_idx] |
1367 | off = * Size of objects stored in this class. Must be multiple * of ZS_ALIGN. * obj_idx & ~PAGE_MASK |
1369 | area = this_cpu_ptr( & per-cpu VM mapping areas for zspage accesses that cross page boundaries ) |
1372 | Else |
1376 | pages[1] = get_next_page(page) |
1381 | The weird & is necessary because sparse considers (void)(var) to be* a direct dereference of percpu variable (var).(per-cpu VM mapping areas for zspage accesses that cross page boundaries ) |
