    sys/fs/msdosfs       msdosfs_lookup.c 
  Disable negative name caching for msdosfs to work around a bug.
  Since the name cache is case-sensitive and msdosfs isn't,
  creating a file 'foo' won't invalidate a negative entry for 'FOO'.
  There are similar problems related to 8.3 filenames.
  A better solution is to override VOP_LOOKUP with a method that
  canonicalizes the name, then calls vfs_cache_lookup().  Unfortunately,
  it's not quite that simple because vfs_cache_lookup() will call
  msdosfs_lookup() on a cache miss, and msdosfs_lookup() needs a way to
  get at the original component name.
