Subject: [PATCH 073/157] mdadm: super-intel fix bad shift
|
||
|
|
||
|
In the expression "1 << i", left shifting by more than 31 bits has undefined behavior.
|
||
|
The shift amount, "i", is as much as 63. The operand has type "int" (32 bits) and will
|
||
|
be shifted as an "int". The fix is to change to a 64 bit int.
|
