...iles changed, 1 insertion(+), 37 deletions(-) Christoph, I guess you didn't mean to send this branch to the mailing list? In any event some of these, like this one, look obvious and I could still grab a few for hmm.git. Let me know what you'd like please Reviewed-by: Jason Gunthorpe <jgg at mellanox.com> Thanks, Jason

From: Jason Gunthorpe <jgg at mellanox.com> The API is a bit complicated for the uses we actually have, and disucssions for simplifying have come up a number of times.

Hi Dan, Jérôme and Jason, below is a series that cleans up the dev_pagemap interface so that it is more easily usable, which removes the need to wrap it in hmm and thus allowing to kill a lot of code Note: this series is on top of Linux 5.2-rc6 and has some minor conflicts with the hmm tree that are easy to resolve.
