To be very honest I also feel very bad doing and DOSing the lists. Sorry to you and everyone else. But I have been sitting on this patch series for last 3-4 merge windows with patches being exactly same/similar. So I have been a little more than desperate to get it in. I really haven't had any meaningful feedback on patch series except stalling just before each merge window for reasons which really shouldn't stall its merge. Sure that's the nature of open source development and it's maintainer's call at the end of the day. And I am new to this. I'll improve. > >First, a modified version of the CFI v23 series was ALREADY SITTING IN >LINUX-NEXT.

Even before this, this patch series has been ignored largely. I don't know how to get attention. All I wanted was either feedback or get it in. And as I said I've been desparate to get it in. Also as I said, I'll improve. > >Please acknowledge that you understand this, ACKed. > > >- Paul
