I've also run across this building the staging-4.9 branch on RHEL7.

Build errors with:
gcc  -m64 -DBUILD_ID -fno-strict-aliasing -std=gnu99 -Wall 
-Wstrict-prototypes -Wdeclaration-after-statement 
-Wno-unused-but-set-variable -Wno-unused-local-typedefs   -O2 
-fomit-frame-pointer 
-D__XEN_INTERFACE_VERSION__=__XEN_LATEST_INTERFACE_VERSION__ -MMD -MF 
.xs-test.o.d -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE   -Werror

BUILDSTDERR: xs-test.c:111:8: error: 'ret' may be used uninitialized in 
this function [-Werror=maybe-uninitialized]
