   7 # On some filesystems (e.g. FreeBSD's ext2 and ufs) directory mtime
   8 # is updated lazily after contents in the directory changes, which
   9 # forces the untracked cache code to take the slow path.  A test
  10 # that wants to make sure that the fast path works correctly should
  11 # call this helper to make mtime of the containing directory in sync
  12 # with the reality before checking the fast path behaviour.
  13 #
  14 # See <20160803174522.5571-1-pclouds@gmail.com> if you want to know
