Hi Jia,
Did you try to come up with a generic interface for this, like
snmp_fold_fields64() (note the fieldS) or snmp_fold_field64_batch() ?
Sounds like we have the same code in several places and seems they all
operate very similarly. They have a percpu table, an identified max, a
destination buffer..
If this is possible, this would reduce the possibility of hiccups in a
particular code.
