From 58097363efc2d53ff5e7379e18955a75679e27eb Mon Sep 17 00:00:00 2001 From: Keir Fraser Date: Tue, 11 Jan 2011 10:32:59 +0000 Subject: [PATCH] xenpaging: print page-in/page-out progress Now that DPRINTF is triggered only when the environment variable XENPAGING_DEBUG is found, make such a debug session actually useful by printing the entire page-out/page-in process. The 'Got event from Xen' message alone is not helpful.
