question about page_to_phys
The page_to_phys is defined as
#define page_to_phys(page) (phys_to_machine(page_to_pseudophys(page)))
so it return machine addresss
while virt_to_phys return psedophys. include/asm-xen/asm-i386/io.h
this is really confusing.
why not define page_to_machine?

[PATCH 0/4] btrfs: out-of-band (aka offline) dedupe v4
Hi,
The following series of patches implements in btrfs an ioctl to do
out-of-band deduplication of file extents.
To be clear, this means that the file system is mounted and running, but the
dedupe is not done during file writes, but after the fact when some
userspace software initiates a dedupe.
The primary patch is loosely based off of one sent by Josef Bacik back
in January, 2011.
