Or in other words what's the point of the mount option? I agree on this. I guess we should instead implement a VFS helper like 'send_error_notification(sb, error_type)'. Then we can teach certain FSes to utilize it. We are particularly interested in FAT, actually. --=20 Best Regards, Artem Bityutskiy (=D0=90=D1=80=D1=82=D1=91=D0=BC =D0=91=D0=B8=D1=82=D1=8E= =D1=86=D0=BA=D0=B8=D0=B9) -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel= " in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
