Subject: [GIT PULL] hardened-usercopy updates for v4.19-rc1
Date: Mon, 13 Aug 2018 13:33:16 -0700 [thread overview]
Message-ID: <20180813203316.GA9967@beast> (raw)
Hi Linus,
Please pull these hardened-usercopy changes for v4.19-rc1. This cleans
up a minor Kconfig issue and adds a kernel boot option for disabling
hardened usercopy for distro users that may have corner-case performance
issues (e.g. high bandwidth small-packet UDP traffic).
Thanks!
-Kees
