From the diff I can see that you also added help texts for two new options (and an old option already had its own help text). But alas "make oldconfig" is unable to show these texts. $ make oldconfig [...] * Restart config... * * * CPU/Task time and stats accounting * Cputime accounting > 1. Simple tick based cputime accounting (TICK_CPU_ACCOUNTING) (NEW) 2. Fine granularity task level IRQ time accounting (IRQ_TIME_ACCOUNTING) choice[1-2]: ? There is no help available for this option. I wonder if make oldconfig could be made smarter about presenting help for choice prompts. As a complication, this particular prompt's set of items differs from architecture to architecture. -- Stefan Richter -=====-===-- =-=- -===- http://arcgraph.de/sr/
