Works for me from openSUSE Tumbleweed to SLE11 SP4 (kernel 3.0). The
build on SLE11 SP2 (also 3.0 but older headers in /usr/include)
fails with unknown MS_PRIVATE and MS_REC in lib/bpf.c
Newer systems have these defined in <sys/mount.h>
Including <linux/fs.h> directly in lib/bpf.c fixes that but if we do
that, a copy of the file would have to be included.

I'm not sure if it is acceptable to modify a file which is supposed to
be a direct copy of kernel uapi header.
