What are your plans for the followup patches that enable reflink+fsdax in XFS? AFAICT that patchset hasn't been posted for while so I don't know what it's status is. Is that patchset anywhere near ready for merge in this cycle? If that patchset is not a candidate for this cycle, then it largely doesn't matter what tree this is merged through as there shouldn't be any major XFS or dax dependencies being built on top of it during this cycle. The filesystem side changes are isolated and won't conflict with other work in XFS, either, so this could easily go through Dan's tree. However, if the reflink enablement is ready to go, then this all needs to be in the XFS tree so that we can run it through filesystem level DAX+reflink testing. That will mean we need this in a stable shared topic branch and tighter co-ordination between the trees. So before we go any further we need to know if the dax+reflink enablement patchset is near being ready to merge.... Cheers, Dave. -- Dave Chinner david@xxxxxxxxxxxxx
