I CC'd your "da...@fromorbit.com" address on the entire set, as well as all the usual lists (linux-xfs, linux-fsdevel, linux-nvdimm, etc). They are also available via the libnvdimm patchwork: https://patchwork.kernel.org/project/linux-nvdimm/list/ or via my tree: https://git.kernel.org/cgit/linux/kernel/git/zwisler/linux.git/log/?h=dax_pmd_v9 The only patch that is different between v8 and v9 is: [PATCH v9 14/16] dax: add struct iomap based DAX PMD support > > Previously we had talked about this series going through the XFS tree, but > > Jan has a patch set that will need to build on this series and it heavily > > modifies the MM code.

I'm confused - I sent v9 of this series out 2 days ago, on Tuesday? I have seen multiple messages from you this week saying you were going to pick this series up, but I saw them all after I had already sent this series out. > The -mm tree is not the place to merge patchsets with dependencies > like this because it's an unstable, rebasing tree.

Really this comes down to a lack of understanding on my part about about which series should be merged via which maintainers, and how stable topic branches can be shared. I didn't realize that if you make a stable branch that could be easily used by other trees, and that for example Jan's MM or ext4 based patches could be merged by another maintainer but be based on your topic branch. Sorry for the confusion, I was just trying to figure out a way that Jan's changes could also be merged. Please do pick up v9 of my PMD set. :) _______________________________________________ Linux-nvdimm mailing list Linux-nvdimm@lists.01.org https://lists.01.org/mailman/listinfo/linux-nvdimm
