It's a stupid copy from arm/include/uapi/asm/fcntl.h and the csky/bits/fcntl.h
in uclibc-ng and glibc are also defined with:
#define __O_DIRECTORY 040000 /* Must be a directory. */
#define __O_NOFOLLOW 0100000 /* Do not follow links. */
#define __O_DIRECT 0200000 /* Direct disk access. */
#define __O_LARGEFILE 0400000
So may I keep it for a while?
(I will let glibc uclibc-ng csky/bits/fcntl.h include the linux/uapi/asm/fcntl.h
first.)
