net-snmp patch to provide disk usage information on tmpfs volumes
By default, net-snmp excludes tmpfs volumes when it provides disk usage information. If tmpfs fills up on an Alpine Linux ramdisk installation, this will often affect services. Therefore, I suggest that we apply the patch below so that we can use SNMP to monitor the free space in Alpine tmpfs filesystems.
