From 96005d20ea03107ea8ec065ff7fdd9dd134c521d Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 19 Sep 2011 12:25:16 -0700 Subject: [PATCH] Make the divelist column naming clearer Currently we use random hard-coded integers, and it's not always clear what is going on. Make it much more explicit with an enumeration of the different divelist columns. And change the column order to make it more logical, and make sure we actually catch all uses while at it.
