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. 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, 291 insertions(+), 273 deletions(-) Changes since v1: - minor comment typo and checkpatch fixes - fix a compile failure for !CONFIG_SHMEM - rebased to the wip/jgg-hmm branch
