Your fix is probably only a workaround. The problem is more complex, because vn_start_write() is able to return 0 and mp == NULL when operation is not supported by file system. I'm not yet sure if we just can't fix vn_start_write() to return EOPNOTSUPP when needed, but there is a special case for this: if (error != EOPNOTSUPP) return (error); return (0); and I must figure out why. There are many vn_start_write() consumers, so this can take a while. Anyway, thank you for your report. -- Pawel Jakub Dawidek http://www.FreeBSD.org pjd@FreeBSD.org http://garage.freebsd.pl FreeBSD committer Am I Evil? Yes, I Am!
