The only reason why the sysfs creation would fail is a kernel bug, so the consequence of your proposal is in fact unfixed kernel bugs. Plus, of course, a driver which doesn't offer the interfaces which it is supposed to offer. Now, we can talk about making those sysfs core functions generate warnings themselves, and we can talk about generating new wrappers around them which generate warnings and which return void, then migrating code over to use those. And we can also talk about blithely ignoring these errors and not telling anyone about our bugs, but nobody should listen to such scandalous ideas. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
