Seems to me the originally-stated problem -- making fsync(2) do what it claims to do -- is not hard at all. Just issue a BIO_FLUSH request as the final step in handling fsync(2). While we're at it, perhaps do the same in close(2). I _hope_ we are already doing it in unmount(2). _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
