As Naoyo has pointed out, the first dependency/conflict Ruan has listed looks trivial to resolve. The second dependency, OTOH, is on a new function added in the patch pointed to. That said, at first glance it looks to be independent of the first two patches in that series so I might just be able to pull that one patch in and have that leave us with a working fsdax+reflink tree. Regardless, I'll wait to see how much work the updated XFS/DAX reflink enablement patchset still requires when Ruan posts it before deciding what to do here. If it isn't going to be a merge candidate, what to do with this patchset is moot because there's little to test without reflink enabled... Cheers, Dave. -- Dave Chinner david@xxxxxxxxxxxxx
