With the new 2.4.23-pa1, I discover that I let badly commented a small chunk a code (just involved toc) and I wrongly merge Randolph's patch (just about a small #ifdef CONFIG_PA20 in 2.4: thanks for your comments :) ). I will advise.

You only want/need self-aligning locks for PA 1.x. You should be able to test this on a PA 2.0 machine if you don't define CONFIG_PA20. Dave -- J.
