    kernel - Improve cache_fullpath() performance
    
    * realpath() now uses cache_fullpath() in the kernel.  This procedure
      was not optimized for performance.
    
    * Fix cache_fullpath() to use a shared ncp lock instead of an exclusive
      one.
    
    * Significantly improves concurrent program executions that use
      realpath() a lot, such as high make -j ops or concurrent makes.
    
    * Change not yet in master but will be soon.
