>Description:
mt_resid is not returned by ioctl MTIOCGET. While the value is 
accessible through ioctl MTIOCERRSTAT, the latter is not portable.
This is not a big issues for read() calls, but is ennoying for MTIOCTOP
operations like fsr, fsf, etc...



>How-To-Repeat:

>Fix:
Update the mt_resid field,in MTIOCGET using the values from last_ctl_resid or
last_io_resid. This supposes that it's remembered somewhere which was
updated last.
