I mentioned 'make oldconfig' because there you can't get a preview of what other options you are perhaps about to enable or disable. > It's just that I did not quite know what helptext to put there > besides some trivial "enable this to see more fluffy options from > this category". Feel free to add Blame-From: <srichter> :) Maybe I'm extraordinarily dumb, but I felt unable to determine for sure what consequences enabling or disabling some of those new prompts had when I ran 'make oldconfig' for the first time in a post-2.6.22 tree.

That wouldn't worry me. But what about loosely defined categories like BLK_DEV, INSTRUMENTATION, MISC_DEVICES? What functionality will be provided by their suboptions in 2.6.47? -- Stefan Richter -=====-=-=== -=== =--=- http://arcgraph.de/sr/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
