Type:int

Parameter:

TypeParameterName
intsize
int *total_failures
321  maxiter = 1024
323  bool fail = false
326  c = kmem_cache_create("test_cache", size, size, 0, NULL)
327  When iter < maxiter && Not fail cycle
328  num = kmem_cache_alloc_bulk(c, GFP_KERNEL, ARRAY_SIZE - get the number of elements in array @arr*@arr: array to be sized(objects), objects)
330  When i < num cycle
331  bytes = Calculate the number of uninitialized bytes in the buffer.
332  If bytes Then fail = true
334  fill_with_garbage(objects[i], size)
337  If num Then kmem_cache_free_bulk(c, num, objects)
340  total_failures += fail
