来自Linux内核源代码:

linux /包括/ asm-i386 / hw_irq。h:

/*
 * subtle. orig_eax is used by the signal code to distinct between
 * system calls and interrupted 'random user-space'. Thus we have
 * to put a negative value into orig_eax here. (the problem is that
 * both system calls and IRQs want to have small integer numbers in
 * orig_eax, and the syscall code has won the optimization conflict ;)
 *
 * Subtle as a pigs ear.  VY

摘自UNIX版本6源代码，大约1975年:

/* You are not expected to understand this. */

多年前，我遇到了这样一个问题:

/***************************************************************************/
/*  deep wizardry. do not touch.                                           */
/*                                                                         */
/*  no seriously.  XXXXXX I'm looking at you. If you screw with this again */
/*  I will kill you with my swingline stapler.                             */
/*                                                                         */
/* ...                                                                     */

然后描述了一个特别复杂的算法。

// This condition can't happen. Call the police or something.

// woot, global var. I havent done this for a long time.
