Hi all, this series is based on a patch from Linus to split the callbacks passed to walk_page_range and walk_page_vma into a separate structure that can be marked const, with various cleanups from me on top. Note that both Thomas and Steven have series touching this area pending, and there are a couple consumer in flux too - the hmm tree already conflicts with this series, and I have potential dma changes on top of the consumers in Thomas and Steven's series, so we'll probably need a git tree similar to the hmm one to synchronize these updates. This series is also available as a git tre here: git://git.infradead.org/users/hch/misc.git pagewalk-cleanup Gitweb: http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/pagewalk-cleanup Diffstat: 14 files changed, 285 insertions(+), 278 deletions(-)
