Hello,

I am a student studying operating systems. I have been to take a look at
the Linux scheduler and I have a few questions and a documentation patch.

1) Why all of the gotos, especially in schedule()? They all seem
to be better replaced with either macros or inline functions or
better yet, conditional else branches.

2) Lines 550-555 state:
        /*
         * We drop the scheduler lock early (it's a global spinlock),
         * thus we have to lock the previous process from getting
         * rescheduled during switch_to().
         */

I do not see this being done. Is this a bug or an old comment?

The documentation patch is against a vanilla 2.3.99pre3 tree.

-Neal
