Is there any particular protocol we should use to avoid stomping on each others toes when working on particular patches? It is quite easy to generate double nasty conflicts when working with patches of patches. I'm currently working through the patch set starting at the top (my patch tool was unhappy with 002-sync-bitops), working down my todo list. bobo at linux:~/paravirt> hg status M 002-sync-bitops.patch M 003-remove-ring0-assumptions.patch Thanks, Zach
