Subject: [PATCHv9-rebased2 00/37] THP-enabled tmpfs/shmem using compound pages
Andrew,
As requested, here's refreshed version of the patchset.
During preparation, Ebru mentionedi (on irc) on that she wanted to withdraw
mm-thp-avoid-unnecessary-swapin-in-khugepaged.patch from mm tree, but it's
difficult in current state of the tree. So I did rebase removing the patch.
The patchset below is aimed to replace patches in your series, staring
with mm-vmstat-calculate-particular-vm-event.patch (it's not necessary
after mm-thp-avoid-unnecessary-swapin-in-khugepaged.patch removal) up to
end of my patchset.
I also took opportunity to address Vlastimil's concern about 'pmd'
re-validiation after mmap_sem drop (you mentioned it in series file).
See patch 05/37.
I did few sanity check. Everything looks good.
Hopefully, I didn't screw up anything on the way. :)
