Re: [B.A.T.M.A.N.] [PATCH 13/26] staging:batman-adv: convert multiple /proc files to use sysfs

Well, it is simple to enable configfs if you need/want batman, right? It's not that much extra kernel code.

If you have 4MB flash for the bootloader, bootloader config, kernel, user space and some data you don't want to add another filesystem just for batman. As hardware development moves on, I defintely see more flexibility regarding these contraints.

...

            following values:
              1 - originator
              2 - TQ (transmit quality) value of originator
              3 - best next hop towards originator
              4 - outgoing iface to reach best next hop
              5 - list of alternative best next hops

Sorry, but sysfs is for "one value per file" attributes, which this one violates.

Actually, this is a good example for our confusion. For this table I used Documentation/ABI/testing/sysfs-block as an example. The very first entry looks exactly like ours ...

Thanks for your quick feedback!
