Current design supports only whole percentages and if userspace needs
more granularity then it has to use usecs.
I agree that usecs cover % usecase and "threshold * win / 100" is
simple enough for userspace to calculate. I'm fine with changing to
usecs only.

Hi Suren,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on linus/master]
[also build test ERROR on v4.20-rc7]
[cannot apply to next-20181218]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system]

Instead of changing cache->align to be aligned to KASAN_SHADOW_SCALE_SIZE
in kasan_cache_create() we can reuse the ARCH_SLAB_MINALIGN macro.

Adding the document to the usb index file and fixing a few
references. Also, exposing the code examples as "literal
blocks" so they are more easy to read.
