    api: versioned symbols in libgfapi.so for compatibility
    
    Use versioned symbols to keep libgfapi at libgfapi.so.0.0.0
    
    Some nits uncovered:
    
    + there are a couple functions declared that do not have an
      associated definition, e.g. glfs_truncate(), glfs_caller_specific_init()
    
    + there are seven private/internal functions used by heal/src/glfsheal
      and the gfapi master xlator (glfs-master.c): glfs_loc_touchup(),
      glfs_active_subvol(), and glfs_subvol_done(), glfs_init_done(),
      glfs_resolve_at(), glfs_free_from_ctx(), and glfs_new_from_ctx();
      which are not declared in glfs.h;
    
    + for this initial pass at versioned symbols, we use the earliest version
      of all public symbols, i.e. those for which there are declarations in
      glfs.h or glfs-handles.h.
      Further investigation as we do backports to 3.6, 3.4, and 3.4
      will be required to determine if older implementations need to
      be preserved (forward ported) and their associated alias(es) and
      symbol version(s) defined.
    
    FWIW, we should consider linking all of our libraries with a map, it'll
    result in a cleaner ABI. Perhaps something for an intern to do or a
    Google Summer of Code project.

This bug is getting closed because a release has been made available that should address the reported issue. In case the problem is still not fixed with glusterfs-3.6.1, please reopen this bug report.

glusterfs-3.6.1 has been announced [1], packages for several distributions should become available in the near future. Keep an eye on the Gluster Users mailinglist [2] and the update infrastructure for your distribution.
