    sys/fs/coda          cnode.h coda_psdev.c coda_subr.c 
                         coda_subr.h coda_vnops.c coda_vnops.h 
    sys/modules/coda     Makefile 
  Log:
  Rather than having the Coda module use its own namecache, use the global
  VFS namecache, as is done by the Coda module on Linux.  Unlike the Coda
  namecache, the global VFS namecache isn't tagged by credential, so use
  ore conservative flushing behavior (for now) when CODA_PURGEUSER is
  issued by Venus.
  
  This improves overall integration with the FreeBSD VFS, including
  allowing __getcwd() to work better, procfs/procstat monitoring, and so
  on.  This improves shell behavior in many cases, and improves ".."
  handling.  It may lead to some slowdown until we've implemented a
  specific access cache, which should net improve performance, but in the
  mean time, lookup access control now always goes to Venus, whereas
  previously it didn't.
