Subject: [PATCH kernel v2 0/2] powerpc/mm/iommu: Put pages on process exit
Date: Wed, 20 Jul 2016 14:34:29 +1000 [thread overview]
Message-ID: <1468989271-753-1-git-send-email-aik@ozlabs.ru> (raw)
This is a fix to a bug when guest memory stays Active
after QEMU process exited. This happened because the QEMU memory context
was not released in a short period of time after QEMU process exited.
More details are in the commit logs.
Please comment. Thanks.
