システムコールとカーネルの関数

システムコールの番号とカーネルソース中でシステムコールを実装している関数を バージョン 2.0, 2.2, 2.4(2.4-test4) に関してまとめた． 表中で______ となっている項目は sys_ni_syscall(void) で実装しているが，呼ぶと エラーを返す．

システムコールの名前は linux/include/asm-i386/unistd.h で定義されている __NR_fork などから __NR_ を除いたもので示している．

2.2系列と2.4系列の差は uid, gid が32ビットに拡張された部分が主で上位互換となっている模様．
