This patchset is intended to clean up the handling of the i_version counter by nfsd. Most of the changes are to internal interfaces. This set is not intended to address crash resilience, or the fact that the counter is bumped before a change and not after. I intend to tackle those in follow-on patchsets. My intention is to get this series included into linux-next soon, with an eye toward merging most of it during the v6.2 merge window. The last patch in the series is probably not suitable for merge as-is, at least until we sort out the semantics we want to present to userland for it.
