From 66c04f4f47f1f8fc55b3cc81df67acac1aa72b8f Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Wed, 9 Nov 2011 08:06:17 -0800 Subject: [PATCH] Fix up the statistics page use of pressure data The statistics page calculates air use separately, and also needs to be fixed up for the split of the pressures into sample-vs-start/end.
