Subject: Please revert 4fd466eb46a6 ("HWPOISON: add memory cgroup filter")
Date: Tue, 28 Jan 2014 16:45:24 -0500 [thread overview]
Message-ID: <20140128214524.GA16060@mtj.dyndns.org> (raw)
Hello, Andi, Wu.
Can you guys please revert 4fd466eb46a6 ("HWPOISON: add memory cgroup
filter"), which reaches into cgroup to extract the inode number and
uses that for filtering? Nobody outside cgroup proper should be
reaching into that. In fact, the hard association between vfs objects
and cgroup objects are going away in the upcoming devel cycle. If you
want to tag on memcg for filtering, please introduce a proper memcg
knob.
Thank you.
