Here is a series of patch. I am absolutely not sure I found all the
filters that could be flagged, but the rest can be done as the need
arises.
Not tested every filter, but it is pretty straightforward.
I could not find how to download your patch series in a format suitable
for git am from the monster, I used the v2 series, but it should not
change anything.
Regards,
