Branch in question still doesn't exist; that was a question, not a description
of what I've already done. I guess I can do what you describe, but... Yuck.
Multiple merges from mainline can create one hell of a mess down the road.
I had to deal with results of exactly that when dwmw2 had dumped the audit
tree into my lap and it had been a huge mess that took quite a while to
untangle ;-/

The same goes for modifications hidden in merge commit, BTW. I know that
Linus seems to be OK with that kind of thing, but... every time I run into
that is when some change is not to be found in git log -p ;-/

Oh, well... I'll probably do that merge of mainline back into write_inode
and try hard to avoid anything similar in the next cycles.
