This happened for a long time, actually in late 2.5.x (that I have started
with). Every time I make some changes to config - or simply do make oldconfig
- - xfs is rebuilt. This happens when there are *no* changes related to xfs
alltogether. E.g. I now applied 2.6.15.1 patch and xfs got rebuilt again.
It may be nitpicking, but it is huge module, I have relatively slow system ans
sometimes want to quickly test some trvial changes. xfs doubles compile time
(at the very least).

The xfs source files do:
#include <version.h>
To gain access to actual kernel release.
So each time you do a change to the tree that causes version.h to be
updated the xfs source files will be recompiled.
Note that version.h includes "UTS_NAME" - unfortunately.
So you will see version.h being updated rather often if you have enabled
the "Automatically append version information to the version string" in
the "General Setup" menu.

Ah, thanks. Now the obvious question is, why in-tree code should bother with
version checking?
The patch removes version check and dependency on linux/version.h from
xfs_dmapi.h.

We really don't need that in mainline - I'll clean this up shortly.
thanks.
