Subject: [PATCH 11/12] lkdtm: move jprobe entry points to start of source
Date: Wed, 6 Jul 2016 15:33:30 -0700 [thread overview]
Message-ID: <1467844411-32373-12-git-send-email-keescook@chromium.org> (raw)
In-Reply-To: <1467844411-32373-1-git-send-email-keescook@chromium.org>
In preparation of referencing the jprobe entry points in a structure,
this moves them to the start of the source since they operate mostly
separately from everything else.
