Hi Marek, Thanks for keeping up this work! I really hope it works out for the next merge window. > TODO (optional): > - implement support for contiguous memory areas placed in HIGHMEM zone > - resolve issue with movable pages with pending io operations Can you clarify these? I believe the contiguous memory areas in highmem is something that should really be after the existing code is merged into the upstream kernel and should better not be listed as TODO here. I haven't followed the last two releases so closely. It seems that in v17 the movable pages with pending i/o was still a major problem but in v18 you added a solution. Is that right? What is still left to be done here then? Arnd
