commit 03be85eb11f756414aafedca22f93a3351b727b8
Author: Samuel Thibault <address@hidden>
Date:   Thu Dec 27 00:00:57 2012 +0100

    Optimise dir-lookup's second-lock
    
    This should avoid some lock contention.
    
    * libdiskfs/dir-lookup.c (diskfs_S_dir_lookup): Before releasing &np->lock
    to get &dnp->lock safely, try to lock &dnp->lock directly.
    * libtreefs/dir-lookup.c (_treefs_s_dir_lookup): Likewise.
