These are octal values, so you really want to use 010000000 instead of
08000000. :-)

While looking at that file further, I noticed these two flags share the same
value. I don't know DMAPI/XDSM, but could they potentially conflict?

#define O_NOATIME       04000000
#define O_INVISIBLE     04000000 /* invisible I/O, for DMAPI/XDSM */
