With a litle luck, e2fsck should be able to repair the file system. mkswap
only initializes the partition, little data should be written to the first
few blocks. This includes the superblock, but you have backups of it every
8192 blocks. So try 'e2fsck -b 8193 /dev/hdwhatever', if a simple e2fsck
failed, and increase to -b 16385 and so on until it works.
But I'd reboot the machine first and start with a boot CD. Depending on the
availability of free space, your free time, and importance of the data, you
probably should backup the partition first, just in case things get messed
up.
