Subject: [PATCH] mm/page_isolation: fix tracepoint to mirror check function behavior
Date: Thu, 17 Mar 2016 18:40:56 +0100 [thread overview]
Message-ID: <1458236456-465-1-git-send-email-l.stach@pengutronix.de> (raw)
Page isolation has not failed if the fin pfn extends beyond the end pfn
and test_pages_isolated checks this correctly. Fix the tracepoint to
report the same result as the actual check function.
