This patchset introduces function kvmalloc and kvmalloc_node. These functions allow reliable allocation of objects of arbitrary size. They attempt to do allocation with kmalloc and if it fails, use vmalloc. Memory allocated with these functions should be freed with kvfree. The patchset makes modification to device mapper to use these functions. Mikulas -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
