Actually, this is not full duplication:
__do_kmalloc(size_t size, gfp_t flags,
void *caller)
and
void *kmalloc(size_t size, gfp_t gfp)
they have different amount of arguments and different arguments names.
But as I see include/linux/slab.h is better place. See patch.
It will be great to create another entry for flags of "kmalloc* family
functions,
so we can avoid duplication of this in __do_kmalloc and kmalloc
comments, but I don't know is it possible with scripts/kernel-doc.
