balloon.c is the core functionality.
xen-balloon.c is the "user interface" parts, i.e. the proc and sys
interfaces.
The stuff in balloon.c has more users than just the user interface
parts. e.g. other drivers want it etc.
See 803eb047a28d239809fff1f87274cdaa94e0d8ea for more info which was
done for the use of e.g. ca47ceaa2c407bbddd395c1807b616042365bd65.
Ian.
