Ensure that the content of these sysfs files is always less than one page. Even if this means truncating. The files in question are scheduled to be moved over to debugfs in the future anyway. Upstream patch: http://git.kernel.org/linus/101545f6fef4a0a3ea8daf0b5b880df2c6a92a69 https://bugzilla.redhat.com/show_bug.cgi?id=576018 Thanks, Eugene
