IMHO I like this change :-) BTW, for snprint() from util.h, it seems 
only to be used by sysfs_print() in syfs.h, would you like to change it 
to use sysfs_emit too ?

Thanks for the patch.

sysfs_print() should also be modified if size is a fixed value PAGE_SIZE, 
but here is param, it would be appreciate if you have better method.

Thanks,
