   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
  15# more.
