I stumbled across this, and it's nice. It's a very straightforward walkthrough of what happens when a small program calls open() and then read(). If you look up today's Linux source code, the code has of course evolved and is a bit more complex, but not a lot more. The nice thing about the 2001 code is that it's still dead-simple. |
