Jeff Layton 638e3e7d94 nfsd: use the getattr operation to fetch i_version ... Now that we can call into vfs_getattr to get the i_version field, use that facility to fetch it instead of doing it in nfsd4_change_attribute. Neil also pointed out recently that IS_I_VERSION directory operations are always logged, and so we only need to mitigate the rollback problem on regular files. Also, we don't need to factor in the ctime when reexporting NFS or Ceph. Set the STATX_CHANGE_COOKIE (and BTIME) bits in the request when we're dealing with a v4 request. Then, instead of looking at IS_I_VERSION when generating the change attr, look at the result mask and only use it if STATX_CHANGE_COOKIE is set. Change nfsd4_change_attribute to only factor in the ctime if it's a regular file and the fs doesn't advertise STATX_ATTR_CHANGE_MONOTONIC.
