Per Persson wrote: [An explanation of __copy_user.] Thank you for the most excellent explanation! I have often wondered if my understanding of that code was correct; now I think I really do know what's going on there. I think it might be very valuable for someone who really understands the GCC extented-asm notation to write some documentation of this sort for the parts of the kernel that rely on it, like switch_to(). It would be a nice addition to the existing inline-asm docs on kernelnewbies.org, which cover the notation, but not how the kernel uses it.
