The change to vfs_bio.c in revision 259200 breaks writing to scsi tape drive on i386 and sparc64 on current. I don't have any other machines to test on. here is example: r259199: (/)4794}mt rew (/)4795}tar cvf /dev/sa0 kernel a kernel r259200: (/)4781}mt rew (/)4782}tar cvf /dev/sa0 kernel a kerneltar: Write error the changes between the two revisions: line 3682 removed: bp->b_resid = bip->bio_resid; /* XXX: remove */ I noticed this when trying to do a dump and getting end of tape error. tried different tape drives , different cables no change. backed out r259200 to 259199 and everything works as before.
