Hi Ira,

Say, in case you or anyone else is up for it: there are still about 
two thirds of the 34 patches that could use a reviewed-by, in this series:

   https://lore.kernel.org/r/20190804224915.28669-1-jhubbard@nvidia.com

...and even reviewing one or two quick ones would help--no need to look at
all of them, especially if several people each look at a few.

Also note that I'm keeping the gup_dma_core branch tracking the latest
linux.git, and it seems to be working pretty well, aside from one warning
that I haven't yet figured out (as per the latest commit):

    git@github.com:johnhubbard/linux.git
   

thanks,
