net: rds: use correct size for max unacked packets and bytes
Max unacked packets/bytes is an int while sizeof(long) was used in the sysctl table. This means that when they were getting read we'd also leak kernel memory to userspace along with the timeout values. Signed-off-by: Sasha Levin <sasha.levin@oracle.com> Signed-off-by: David S.
