While I'm running the Plus kernel, it has the same files. What I'm seeing here is that fence.h has been renamed in the 693 kernel to dma-fence.h:

# locate fence.h

/usr/src/kernels/3.10.0-514.26.2.el7.centos.plus.x86_64/include/linux/fence.h
/usr/src/kernels/3.10.0-514.26.2.el7.centos.plus.x86_64/include/linux/seqno-fence.h
/usr/src/kernels/3.10.0-514.26.2.el7.centos.plus.x86_64/include/trace/events/fence.h
/usr/src/kernels/3.10.0-693.2.2.el7.centos.plus.x86_64/include/linux/dma-fence.h
/usr/src/kernels/3.10.0-693.2.2.el7.centos.plus.x86_64/include/linux/seqno-fence.h
/usr/src/kernels/3.10.0-693.2.2.el7.centos.plus.x86_64/include/trace/events/dma_fence.h

Looks like upstream renamed it for some reason.
