[PATCH v7 0/9] fs: clean up handling of i_version counter

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

Jeff Layton (9):
  fs: uninline inode_query_iversion
  fs: clarify when the i_version counter must be updated
  vfs: plumb i_version handling into struct kstat
  nfs: report the inode version in getattr if requested
  ceph: report the inode version in getattr if requested
  nfsd: move nfsd4_change_attribute to nfsfh.c
  nfsd: use the getattr operation to fetch i_version
  nfsd: remove fetch_iversion export operation
  vfs: expose STATX_VERSION to userland
