1. (6 points) Fill the following table by applying the pattern (discussed in the class) to determine the feasibility of execution sequences in dskqopt for each of its three callers: dsread, dswrite, and dsksync Feasible or not when called from dswrite dsksync dsread Governing Conditions in dskqopt drptr->drop==DSYNC || (drptr->drop==DREAD && p->drop==DREAD) ==== drptr->drop DSEEK p->drop == DSEEK p->drop==DWRITE && drptr->drop==DWRITE drptr->drop==DREAD && p->drop==DWRITE drptr->drop==DWRITE && p->drop==DREAD)
