[PATCH] cut'n' paste bug in fold_field()

[Sridhar Samudrala <sri@xxxxxxxxxx>]

Attached is a small patch for a cut'n'paste bug in linux 2.5.59
   net/ipv4/proc.c:fold_field()
This causes some /proc/net counters that are incremented in BH to be counted
twice and the counters incremented in user context not counted.

The same routine(fold_field()) is duplicated in net/ipv6/proc.c, but it doesn't
have the bug.
Could we convert this to a static inline and move to a header file to avoid
the duplication and 'sctp' too can use it.

Thanks
