Subject: [PATCH 04/12] xenpaging: print page-in/page-out progress
Date: Mon, 10 Jan 2011 17:43:49 +0100 [thread overview]
Message-ID: <20110110164347.069903765@aepfle.de> (raw)
In-Reply-To: 20110110164345.521919826@aepfle.de
[-- Attachment #1: xen-unstable.xenpaging.print-pageout-pagein-progress.patch --]
[-- Type: text/plain, Size: 978 bytes --]
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.
