Shorter version, why do you think it is?  :)

Have you done some testing of the amount of memory that sysfs entries
consume and found any problems with it?  Remember, a s390 system with
20000 disks works just fine with a very little memory footprint, a lot
of work has gone into making sysfs consume tiny amounts of memory.

thanks,
