Subject: [PATCH] memory_hotplug: add missing newlines to debugging output
Date: Tue, 18 Dec 2018 17:23:07 +0100
Message-ID: <> (raw)

From: Michal Hocko <>

pages_correctly_probed is missing new lines which means that the line is
not printed rightaway but it rather waits for additional printks.

Add \n to all three messages in pages_correctly_probed.

Fixes: b77eab7079d9 ("mm/memory_hotplug: optimize probe routine")
