I'm trying to appear to be an incompetent maintainer so that someone will offer to take over. It isn't working yet. I'm probably scuttling the attempt just by replying to this email - drat. >=20 > I have attached the patch set in one big patch for 3.5. Please do not > use it since I am not sure if it is correct.

Maybe if they get posted again I'll feel guilty and do something about them. One issue that needs to be fixed is that a few places assumed that the "discard_zeros_data" flag is always set, which is not the case (else we wouldn't have that flag). That was only a couple of places though, not a wide spread problem.
