Message

David Disseldorp April 16, 2019, 5:26 p.m. UTC

This patchset adds a "ceph.snap.btime" vxattr to snapshot files and
directories, when run alongside an MDS that provides InodeStat v3
information as implemented in https://github.com/ceph/ceph/pull/27077 .

Changes since v1:
- add fix for listxattr vxattr buffer length calculations
  + this bug caused breakage for non-hidden exists_cb() vxattrs
- rebase against current mainline

----------------------------------------------------------------

      ceph: clean up ceph.dir.pin vxattr name sizeof()
      ceph: carry snapshot creation time with inodes
      ceph: add ceph.snap.btime vxattr
      ceph: fix listxattr vxattr buffer length calculation
      ceph: remove unused vxattr length helpers
