Thanks for reporting.

These constants were defined in Linux 2.6.23 and 2.6.38.

It should be OK.

I think we are just missing
	#include <linux/falloc.h>

Currently there is a bug filed in glibc here for the exact same kernel version.

The man page says: "The FALLOC_FL_* flags are defined in glibc headers
only since version 2.18."

I guess we can workaround with a direct include.
