Modified files:
sys/kern subr_diskslice.c
Log:
Fixed overflow in the bounds checking in dscheck(). It assumed that
daadr_t is no larger than a long, and some other relatively harmless
things (*blush*). Overflow for subtracting a daddr_t from a u_long
caused "truncation" of the i/o for attempts to access blocks beyond
the end of the actually cause expansion of the i/o to a preposterous
size.
