It's a block device layer thing, so it doesn't interact
with the VFS. What the LVM layer _seems_ to do is simply
remap an IO request to the device it's supposed to go to
and let the request get into the IO layer again...

(then again, I could be wrong here, the LVM code isn't
the easiest to wade through)
