Subject: [GIT PULL] gcc-plugins updates for v4.11-rc1
Hi,
Please pull these gcc-plugins changes for v4.11-rc1. This includes two new
plugins for the upstream kernel: structleak and initify. The structleak
plugin performs forced initialization of certain structures to avoid
possible information exposures to userspace. The initify plugin performs
analysis to find functions and strings that can be marked as __init or
__exit to reduce the runtime size of the kernel.
Thanks!
-Kees
