Well, I can guarantee that the write(2) into fusefs was not interrupted if you did not specify "-o intr". I know, because I wrote that code. You would need to use "-o intr" whether you mount by invoking mount or ntfs-3g. But cp probably only copies a few KB to a few hundred KB at a time. So even without "-o intr", a signal would probably feel fairly responsive. -Alan _______________________________________________ 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"
