    Subject[PATCH v3] Documentation: remove magic number doc
    The entire file blames back to the start of git
    (minus whitespace from the RST translation and a typo fix):
    * there are changelog comments for March 1994 through to Linux 2.5.74
    * struct tty_ldisc is two pointers nowadays, so naturally no magic
    * GDA_MAGIC is defined but unused, and it's been this way
    since start-of-git
    * M3_CARD_MAGIC isn't defined, because
    commit d56b9b9c464a ("[PATCH] The scheduled removal of some OSS
    drivers") removed the entire driver in 2006
    * CS_CARD_MAGIC likewise since
    commit b5d425c97f7d ("more scheduled OSS driver removal") in 2007
    * KMALLOC_MAGIC and VMALLOC_MAGIC were removed in
    commit e38e0cfa48ac ("[ALSA] Remove kmalloc wrappers"),
    six months after start of git
    * SLAB_C_MAGIC has never even appeared in git
    (removed in 2.4.0-test3pre6)

    At a glance, the only ones still in use are in drivers which are mostly
    untouched since git (TTY, SLIP,
    SCSI (drivers/scsi/{arm/queue.c,ncr53c8xx.c}), &c.).

    A rough estimate of magic numbers in the kernel is obtained by:
    # git grep define | grep '_MAGIC\b' |
    grep -ve IOC -e ^tools/ -e '_IO[(WR]' -e _SUPER | wc -l
    780
    Note that the word 'magic' may have different meaning from magic
    number context.
    There are also magic numbers which aren't listed here, like
    SR_EEPROM_MAGIC, L2TP_TUNNEL_MAGIC, and MD_SB_MAGIC.

    Therefore, magic-number.rst is a low-value historial relic at best and
    misleading cruft at worst, so remove the documentation.

    v2: better subject line, per Bagas Sanjaya
    problem list in message reworded for clarity
    v3: 12-character SHAs, message wording from Bagas Sanjaya

    They didn't, but the constants did.
    Removed as irrelevant since that happened pre-git.

    -Linux magic numbers
    -===================
    -
    -This file is a registry of magic numbers which are in use. When you
    -add a magic number to a structure, you should also add it to this
    -file, since it is best if the magic numbers used by various structures
    -are unique.
    -
    -It is a **very** good idea to protect kernel data structures with magic
    -numbers. This allows you to check at run time whether (a) a structure
    -has been clobbered, or (b) you've passed the wrong structure to a
    -routine. This last is especially useful --- particularly when you are
    -passing pointers to structures via a void * pointer. The tty code,
    -for example, does this frequently to pass driver-specific and line
    -discipline-specific structures back and forth.
    -
    -The way to use magic numbers is to declare them at the beginning of
    -the structure, like so::
    -
    - struct tty_ldisc {
    - int magic;
    - ...
    - };
    -
    -Please follow this discipline when you are adding future enhancements
    -to the kernel! It has saved me countless hours of debugging,
    -especially in the screwy cases where an array has been overrun and
    -structures following the array have been overwritten. Using this
    -discipline, these cases get detected quickly and safely.

    - The magic table is current to Linux 2.1.55.

    - <mailto:mec@shout.net>
    - 22 Sep 1997
    -
    - Now it should be up to date with Linux 2.1.112. Because
    - we are in feature freeze time it is very unlikely that
    - something will change before 2.2.x. The entries are
    - sorted by number field.

    -
    - Updated the magic table to Linux 2.5.45. Right over the feature freeze,
    - but it is possible that some new magic numbers will sneak into the
    - kernel before 2.6.x yet.

    -I numeri magici di Linux
    -========================
    -
    -Questo documento è un registro dei numeri magici in uso. Quando
    -aggiungete un numero magico ad una struttura, dovreste aggiungerlo anche
    -a questo documento; la cosa migliore è che tutti i numeri magici usati
    -dalle varie strutture siano unici.
    -
    -È **davvero** un'ottima idea proteggere le strutture dati del kernel con
    -dei numeri magici. Questo vi permette in fase d'esecuzione di (a) verificare
    -se una struttura è stata malmenata, o (b) avete passato a una procedura la
    -struttura errata. Quest'ultimo è molto utile - particolarmente quando si passa
    -una struttura dati tramite un puntatore void \*. Il codice tty, per esempio,
    -effettua questa operazione con regolarità passando avanti e indietro le
    -strutture specifiche per driver e discipline.
    -
    -Per utilizzare un numero magico, dovete dichiararlo all'inizio della struttura
    -dati, come di seguito::
    -
    - struct tty_ldisc {
    - int magic;
    - ...
    - };
    -
    -Per favore, seguite questa direttiva quando aggiungerete migliorie al kernel!
    -Mi ha risparmiato un numero illimitato di ore di debug, specialmente nei casi
    -più ostici dove si è andati oltre la dimensione di un vettore e la struttura
    -dati che lo seguiva in memoria è stata sovrascritta. Seguendo questa
    -direttiva, questi casi vengono identificati velocemente e in sicurezza.

    -Linux 魔术数
    -============
    -
    -这个文件是有关当前使用的魔术值注册表。当你给一个结构添加了一个魔术值,你也应该把这个魔术值添加到这个文件,因为我们最好把用于各种结构的魔术值统一起来。
    -
    -使用魔术值来保护内核数据结构是一个非常好的主意。这就允许你在运行期检查(a)一个结构是否已经被攻击,或者(b)你已经给一个例行程序通过了一个错误的结构。后一种情况特别地有用---特别是当你通过一个空指针指向结构体的时候。tty源码,例如,经常通过特定驱动使用这种方法并且反复地排列特定方面的结构。
    -
    -使用魔术值的方法是在结构的开始处声明的,如下::
    -
    - struct tty_ldisc {
    - int magic;
    - ...
    - };
    -
    -当你以后给内核添加增强功能的时候,请遵守这条规则!这样就会节省数不清的调试时间,特别是一些古怪的情况,例如,数组超出范围并且重新写了超出部分。遵守这个规则,‪这些情况可以被快速地,安全地避免。

    -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。

    -請注意,在聲音記憶管理中仍然有一些特殊的爲每個驅動定義的魔術值。查看include/sound/sndmagic.h來獲取他們完整的列表信息。很多OSS聲音驅動擁有自己從音效卡PCI ID構建的魔術值-他們也沒有被列在這裡。
    -
    -IrDA子系統也使用了大量的自己的魔術值,查看include/net/irda/irda.h來獲取他們完整的信息。
    -
    -HFS是另外一個比較大的使用魔術值的文件系統-你可以在fs/hfs/hfs.h中找到他們。
