Looks that Farm uses it wrong. I include attr/xattr.h as man 2 getxattr
suggests.

When I tried sys/xattr.h, I have to additionally manually change XNOATTR
into *XNODATA* or meet an compile error.

So, I just wonder which is right way to use getxattr/setxattr system
call? If we are supposed to use sys/xattr.h, I think there is some
manual accessible to tell that we might have to use XNODATA instead of
XNOATTR for error check. Do I miss anything?

Thanks,
