Error on Centos 7.4 Kernel 3.10.0

[PascalGasser]

Hello,
I have this issue on a Centos 7.4.1708. Kernel 3.10.0-693.5.2.el7.x86_64
I have see the post #223 but it's for the 7.3 and not the 7.4.

You need to change this 4 files :

src/flashcache_conf.c
src/flashcache_ioctl.c
src/flashcache_ioctl.h
src/utils/flashcache_setioctl.c

With the source found in the #223

And after it work perfect with the centos 7.4 :-)

The problem still exists on master branch, anyone can fix it?
