   2 Features:
   3
   4 * config: configs that do not need to be matched by fnmatch() could be using a
   5   vector instead of a list. This way we could search in it by calling
   6   bsearch().
   7
   8 * config: load on demand
   9
  10 * index: drop the "open(), seek(), read()" implementation and use another one
  11   with mmap(). When lookup() is called and the file is not mmaped, mmap it.
  12
  13 * provide a kmod_preload_resources() so configs are parsed and files are mmaped
  14   with MAP_POPULATE | MAP_LOCKED. Maybe it's a good idea to have a
  15   kmod_unload_resources() too.
  16
  17 * kmod_module: create a mempool with live and recently de-allocated modules.
  18   This way we don't have to create a new one, parse dependencies and whatnot.
  19   Just pick the already created node.
  20
  21 * kmod_module: apply blacklist on module lookup. What's best? Return the whole
  22   list and provide functions like kmod_module_filter_* or return the list
  23   already filtered?
  24   ^-- investigate the best API
  25
  26 * insmod and rmmod with dependency handling. Maybe this should be done by the
  27   binary, and it's sufficient to return only the lists from lookups.
  28   ^-- investigate the best API
  29
  30 * when preloading stuff, give the possibility to preload binary files. We need
  31   to create alternative index_search* functions to operate on mmapped files.
  32   Then on ctx creation we mmap all the files
  33
  34 * kmod_module: calculate fields on demand if not available:
  35         - name
  36         - path
  37         - dependency
  38
  39 * index: check implementations in order to allocate less stuff. There some
  40   malloc()s that could be avoided
