The fun part is that the Linux folks are already discussing adding flags. I don't know if they are already in Linux-next (or whatever they call their next release), but it sounded like they were headed that way. As such, I thought ignoring "flags" would be easier than returning EINVAL for code that works on Linux. However, I can see the counter argument, which is "returning EINVAL will indicate that the Linux flag isn't used on FreeBSD", so that developers will become aware of that. What do others think w.r.t. which is the better approach? rick _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
