Subject: [PATCH v2 0/2] kasan: fix memory notifier handling
Date: Tue, 22 May 2018 12:07:54 +0200	[thread overview]
Message-ID: <20180522100756.18478-1-david@redhat.com> (raw)

If onlining of pages fails (is canceled), we don't properly free up memory.
Also, the memory hotplug notifier is not registered early enough, still
failing on certain setups where memory is detected, added and onlined
early.

v1 -> v2:
- s/MEM_CANCEL_OFFLINE/MEM_CANCEL_ONLINE

David Hildenbrand (2):
  kasan: free allocated shadow memory on MEM_CANCEL_ONLINE
  kasan: fix memory hotplug during boot
