(2) When a bit device is designated for
The number of bits by which a rotation is carried out is the remainder of n/(specified number of bits).
For example, when n
rotated 3 bits.
(3) Specify any of 0 to 15 as n.
If the value specified as n is 16 or greater, the remainder of n / 16 is used for rotation.
For example, when n
