    Avoid superfluous locking of node
    
    * libdiskfs/io-restrict-auth.c (diskfs_S_io_restrict_auth): Do not
    lock the associated node.  No operation here needs synchronization.
    * libnetfs/io-restrict-auth.c (netfs_S_io_restrict_auth): Likewise.

commit 55f23b9e82d6086bc4f21411e25aaf9746928d79
Author: Justus Winter <address@hidden>
Date:   Sat Apr 23 17:39:47 2016 +0200

    utils/settrans: implement active translator stacking
    
    * utils/settrans.c (OPT_STACK): New macro.
    (options): New option.
    (main): Handle new option.
    (open_node): Use different flags for the lookup of the underlying
    node.

    libnetfs: treat disconnected shadow roots as virtual roots
    
    * libnetfs/dir-lookup.c (netfs_S_dir_lookup): Treat a shadow_root with
    null shadow_root_parent as a "virtual root".
    
    Analog to 6875a586.

commit 13efe6721a370c38b65e0da3d33f310f42cfa05f
Author: Justus Winter <address@hidden>
Date:   Mon Apr 18 21:53:28 2016 +0200

    Unify the short-circuit translator logic
    
    * libdiskfs/dir-lookup.c (short_circuited_callback1): Move function to
    libfshelp.
    (diskfs_S_dir_lookup): Use the function from libfshelp instead.
    * libdiskfs/fsys-getroot.c (diskfs_S_fsys_getroot): Adapt accordingly.
    * libdiskfs/trans-callback.c (_diskfs_translator_callback2_fn): Likewise.
    * libfshelp/fetch-root.c (fshelp_short_circuited_callback1): New function.
    * libfshelp/fshelp.h (struct fshelp_stat_cookie): New definition.
    (fshelp_short_circuited_callback1): New prototype.
    * libnetfs/dir-lookup.c (short_circuited_callback1): Drop function.
    (netfs_S_dir_lookup): Use the function from libfshelp instead.
    * libnetfs/fsys-getroot.c (netfs_S_fsys_getroot): Adapt accordingly.
    * libnetfs/trans-callback.c (_netfs_translator_callback2_fn): Likewise.

commit 3416078aa58b095566e559b7dbd9c9da4d1fc5d5
Author: Justus Winter <address@hidden>
Date:   Mon Apr 18 19:33:03 2016 +0200

    libdiskfs: cosmetic changes
    
    * libdiskfs/dir-lookup.c (diskfs_S_dir_lookup): Rename identifiers to
    be more idiomatic and closer to libnetfs and the interface
    specification.  Massage the code so that it aligns closer with the
    dir_lookup server function in libnetfs.  It should not change the
    behavior.
