Hi Andrew, * !

I am experiencing quite a few strange error with my DAT tape since about
this checkin. A kernel from the beginning of July works flawlessly with the
drive and the tape.

Symptoms:
    I/O errors claimed where no real I/O error where. Possibly
   triggered by length indicator mismatches reported by the drive. These
  are ok for variable block size formatted media. Those indications where
  handled properly at the beginning of July and years before.

The dmesg output shows a READ that is terminated with an I/O error,
but data was transferred (with the size mismatch indication).
The requested block was just too big - a smaller block was read.

The second attempt with a block too small was terminated with a panicinstead

of an I/O error.

Could somebody check what broke st.c between beginning of July and now ?
Currently st.c is unusable for variable block size tape I/O.

dmesg atteched.

Regards,
 Frank

Log Message:
It's not a good idea for device drivers to modify b_flags, as they don't
need to understand the locking around that field. Instead of setting
B_ERROR, set b_error instead. b_error is 'owned' by whoever completes
the I/O request.
