__volatile__ __asm__

volatile is a C keyword, and programmers know better than using asm as an identifier. Why do people insist on using double underscores around them, especially Linux kernel developers?

Also, why do people use things like __attribute__((aligned(n))) instead of defining a macro ALIGNED(n)?

The main legitimate use of volatile nowadays is to prevent the compiler from removing asm sections or moving them around.

Fuck off you fucking shiteater.
