You bet.

First of all, there is such ioctl, but it's quite a mess (as any ioctl,
for that matter). FIBMAP. However, hacking _that_ into tar is idiocy - you
don't want to pollute the generic tool with such mess. Let it do _one_
thing, and do it good. GNU tar is already featuritis-ridden - just check
the list of options (oops, no decent manpage - GNU project at its usual)
and you'll see what I mean.
Look: if you need incrementals - make a tool that would take whatever data
it wants to keep and print the list of files due to be backed up. And
feed the results to tar/cpio/whatever. It's not like the idea of pipes was
new, after all.
BTW, no other tar does -g, and rightfully so. It's _not_ a work for tar
- it's (a) format-independent, (b) useful for other purposes, (c) can be
trivially off-loaded into separate program, (d) may require modifications
for oddball filesystems/local policy/whatever and those changes have
_nothing_ with tar. I.e. it should be done separately. But GNU folks love
monolitic monsters... Could somebody tell RMS about pipes and fork(2),
please?
