From: Matthew Wilcox <willy@xxxxxxxxxxxxxxx> Hi Andrew, I believe this entire patch series should apply cleanly to your tree. The first patch I have already sent to Ted. It should be applied for 4.2. Patch 4 depends on patch 1 having been applied first, patch 5 depends on patch 4, and patch 6 depends on patch 5, so I can't wait for those patches to go in via the ext4 tree. Most of these patches aren't needed for 4.2 and earlier, because they pertain to the PMD support which is only in the -mm tree. Kirill A.
