My guess is that the filesystem change notification would be a better

This is also something (but just a bit) different - I don't need "change notification" but "pre-change notification" ;)

Except for exactly two cases, pre-change and post-change and the same,
just off-by-one. So you would need a bootup/mount/whenever special
case now, is that a big problem?
Probably my english is bad but I don't understand what are you trying to say (except the german part ;-))
A bit more about pre/post-change (if this is what are you trying to say) - I need allways pre-change because after file is changed I can no longer get original (pre-change) version of file which I need for snapshot.
without system call anyway (think mmaped file where the dirtying doesnt'
involve a syscall
