I don't think it's worth to change sys/kern/sys_pipe.c just to implement linux_pipe2 in linuxator. You can just revert the changes in sys_pipe.c and call kern_fcntl in linux_pipe2 to set appropriate flags for the pipes after you created them with kern_pipe. Please, take a look at this patch http://www.trematerra.net/patches/linux_pipe2.patch It's only test-compiled though.
