Subject[PATCH v4 05/19] afs: convert to new i_version API
Date
From: Jeff Layton <jlayton@redhat.com>

For AFS, it's generally treated as an opaque value, so we use the
*_raw variants of the API here.

Note that AFS has quite a different definition for this counter. AFS
only increments it on changes to the data, not for the metadata. We'll
need to reconcile that somehow if we ever want to present this to
userspace via statx.
