Sorry, I missed this patchset. I tried applying this patchset on top of XFS'
current for-next branch. But it failed due to merge conflicts. I would suggest
that you should wait until the "shmem patches" impasse gets resolved and
for-next branch becomes stable.
I will respond to this mail as to when you can rebase your patchset on
for-next and either send a pull request or post the rebased version of the
patchset to the mailing list.
