and you're now done. Tadaa! You have a pre-emptive UP kernel. Add a few months of debugging (because something _will_ crop up, or my name isn't Billy-Bob).
Linus,
I think this is a great idea, as it will catch all sorts of places where we've been slopping about SMP races, by exposing them in the UP kernel. However, is now (just before 2.4) the best time to be doing this? I fear that there may be plenty of places hiding in the kernel where we aren't adequately proteccting shared data structures.
We might be better off holding off until 2.5 to make such change. Then as bugs are found in the 2.5 tree (and I have no doubt that we will have them!), we can backport the fixes to the 2.4 tree. This way at least we're not potentially compromising the stability of 2.4 UP kernels just before the 2.4 release.....
