Subject: Bogus disk geometry on large disks
From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>
We currently stuff a truncated size into the geometry logic and return the
result which can produce bizarre reports for a 4Tb array. Since that
mapping logic isn't useful for disks that big don't try and map this way at
all.
