Please go through the various fixes which we had as well: Yes i will not forget them and i will try to get more config build to be sure there is not issue. I need to register a tree with the rand-config builder but i lack place where i can host a https tree (i believe this is a requirement). > > mm-hmm-use-reference-counting-for-hmm-struct.patch > mm-hmm-do-not-erase-snapshot-when-a-range-is-invalidated.patch > mm-hmm-improve-and-rename-hmm_vma_get_pfns-to-hmm_range_snapshot.patch > mm-hmm-improve-and-rename-hmm_vma_fault-to-hmm_range_fault.patch > mm-hmm-improve-driver-api-to-work-and-wait-over-a-range.patch > mm-hmm-improve-driver-api-to-work-and-wait-over-a-range-fix.patch > mm-hmm-improve-driver-api-to-work-and-wait-over-a-range-fix-fix.patch > mm-hmm-add-default-fault-flags-to-avoid-the-need-to-pre-fill-pfns-arrays.patch > mm-hmm-add-an-helper-function-that-fault-pages-and-map-them-to-a-device.patch > mm-hmm-support-hugetlbfs-snap-shoting-faulting-and-dma-mapping.patch > mm-hmm-allow-to-mirror-vma-of-a-file-on-a-dax-backed-filesystem.patch > mm-hmm-allow-to-mirror-vma-of-a-file-on-a-dax-backed-filesystem-fix.patch > mm-hmm-allow-to-mirror-vma-of-a-file-on-a-dax-backed-filesystem-fix-2.patch > mm-hmm-add-helpers-for-driver-to-safely-take-the-mmap_sem.patch > > Also, the discussion regarding [07/10] is substantial and is ongoing so > please let's push along wth that. I can move it as last patch in the serie but it is needed for ODP RDMA convertion too. Otherwise i will just move that code into the ODP RDMA code and will have to move it again into HMM code once i am done with the nouveau changes and in the meantime i expect other driver will want to use this 2 helpers too. > > What is the review/discussion status of "[PATCH 09/10] mm/hmm: allow to > mirror vma of a file on a DAX backed filesystem"? I explained that this is needed for the ODP RDMA convertion as ODP RDMA does supported DAX today and thus i can not push that convertion without that support as otherwise i would regress RDMA ODP. Also this is to be use by nouveau which is upstream and there is no reasons to not support vma that happens to be mmap of a file on a file- system that is using a DAX block device. I do not think Dan had any comment code wise, i think he was complaining about the wording of the commit not being clear and i proposed an updated wording that he seemed to like. Cheers, Jérôme
