Name:Add a shrinker callback to be called from the vm.

Proto:int prealloc_shrinker(struct shrinker *shrinker)

Type:int

Parameter:

Type	Parameter	Name
struct shrinker *	shrinker

352

size = size of bjs pending delete, per node

354

If flags & Flags Then size *= nr_node_ids

357

bjs pending delete, per node = kzalloc - allocate memory. The memory is set to zero.*@size: how many bytes of memory are required.*@flags: the type of memory to allocate (see kmalloc).

358

If Not bjs pending delete, per node Then Return -ENOMEM

361

If flags & SHRINKER_MEMCG_AWARE Then

362

If prealloc_memcg_shrinker(shrinker) Then Go to free_deferred

366

Return 0

368

free_deferred :

369

kfree - free previously allocated memory*@objp: pointer returned by kmalloc.* If @objp is NULL, no operation is performed.* Don't free memory not originally allocated by kmalloc()* or you will run into trouble.

370

bjs pending delete, per node = NULL
