Subject: [PATCH 0/3] Do not map unaccepted memory
Date: Wed, 6 Sep 2023 10:38:59 +0300 [thread overview]
Message-ID: <20230906073902.4229-1-adrian.hunter@intel.com> (raw)
Hi
Support for unaccepted memory was added recently, refer commit
dcdfdd40fa82 ("mm: Add support for unaccepted memory"), whereby
a virtual machine may need to accept memory before it can be used.
Plug a few gaps where RAM is exposed without checking if it is
unaccepted memory.
Adrian Hunter (3):
proc/vmcore: Do not map unaccepted memory
proc/kcore: Do not map unaccepted memory
/dev/mem: Do not map unaccepted memory
drivers/char/mem.c | 9 +++++++--
fs/proc/kcore.c | 10 +++++++++-
fs/proc/vmcore.c | 15 ++++++++++++---
