Any objections towards the approach taken by the patchset to allow upgrading older V5 filesystems. 2. "Btree cursor rework" patchset on which large extent counter patchset will be based on. If you think btree cursor rework patchset can be completed quickly enough to give me time (which shouldn't be more than a week) to rebase the large extent counter patch series and test it, then I think my patchset can be considered for merging. One of the things that I missed was that bulkstat ioctl calls made by libfrog had to check for the presence of XFS_FSOP_GEOM_FLAGS_NREXT64 before including the newly defined XFS_BULK_IREQ_BULKSTAT and XFS_BULK_IREQ_BULKSTAT_NREXT64 flags in the bulkstat header.
