Hi,
The "track FOLL_PIN pages" would have been the very next patch, but it is
not included here because I'm still debugging a bug report from Leon.
Let's get all of the prerequisite work (it's been reviewed) into the tree
so that future reviews are easier. It's clear that any fixes that are
required to the tracking patch, won't affect these patches here.
This implements an API naming change (put_user_page*() -->
unpin_user_page*()), and also adds FOLL_PIN page support, up to
*but not including* actually tracking FOLL_PIN pages. It extends
the FOLL_PIN support to a few select subsystems. More subsystems will
be added in follow up work.
Hi Andrew and all,
To clarify: I'm hoping that this series can go into 5.6.
Meanwhile, I'm working on tracking down and solving the problem that Leon
reported, in the "track FOLL_PIN pages" patch, and that patch is not part of
this series.
thanks,
