* kmalloc is the normal method of allocating memory
* for objects smaller than page size in the kernel.
*
+ * The allocated object address is aligned to at least ARCH_KMALLOC_MINALIGN
+ * bytes. For @size of power of two bytes, the alignment is also guaranteed
+ * to be at least to the size.

* The @flags argument may be one of the GFP flags defined at
* include/linux/gfp.h and described at
