Hello,
To avoid the confusion, let me resend everything (except the 1st patch
you already applied) with v2 tag.
Changes:
4/7 - fix the typo in changelog, add the ack from Srikar
6/7 - by discussion with you and Namhyung: pass dir rather
then system, update replace_system_preds() as well.
7/7 - new, cosmetic/trivial.
I tried to play with "filter" files, everything seems to work with the
additional debugging patch below.
Oleg.
