Sure, this can still be kept in a dark corner, no need for it to clutter or get in the way of creating cleaner APIs. That's one of the goals here, and going through with these changes should help us get there.

Assuming that dell-rbu is the only in-tree legitimate user of the userhelper code, I'm curious if the code itself could simply move into that driver. It might help prevent the spread of reliance on an API we don't want to see grow in usage. We'd probably need to evaluate if the two new users could migrate off that. > Also, for some devices / use cases, the usermode helper is the solution > (think async loading of firmware when the host wants to do it.) Are any of those use cases in the kernel today, aside from dell-rbu? Would Luis' async mode to system data suffice? josh -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
