- Note that there are also defined special per-driver magic numbers in sound
- memory management. See ``include/sound/sndmagic.h`` for complete list of them. Many
- OSS sound drivers have their magic numbers constructed from the soundcard PCI
- ID - these are not listed here as well.
-
- HFS is another larger user of magic numbers - you can find them in
- ``fs/hfs/hfs.h``.

- Da notare che ci sono anche dei numeri magici specifici per driver nel
- *sound memory management*. Consultate ``include/sound/sndmagic.h`` per una
- lista completa. Molti driver audio OSS hanno i loro numeri magici costruiti a
- partire dall'identificativo PCI della scheda audio - nemmeno questi sono
- elencati in questo file.
-
- Il file-system HFS è un altro grande utilizzatore di numeri magici - potete
- trovarli qui ``fs/hfs/hfs.h``.

- 请注意，在声音记忆管理中仍然有一些特殊的为每个驱动定义的魔术值。查看include/sound/sndmagic.h来获取他们完整的列表信息。很多OSS声音驱动拥有自己从声卡PCI ID构建的魔术值-他们也没有被列在这里。
-
- IrDA子系统也使用了大量的自己的魔术值，查看include/net/irda/irda.h来获取他们完整的信息。
-
- HFS是另外一个比较大的使用魔术值的文件系统-你可以在fs/hfs/hfs.h中找到他们。
