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.
