You are right, roger. Thanks.
domid is a u16, it will occupy 5 characters at most. So the biggest
length of blkback name is 8+5+5=18.
At this situation, define BLKBACK_NAME_LEN macro to be 20 is safe.

The blkback name is like blkback.domid.xvd[a-z], if domid has three digits
(means larger than 100), then the backmost xvd wouldn't be fully shown.
Define a BLKBACK_NAME_LEN macro which is (TASK_COMM_LEN * 2), enlarge the
array size of blkback name, so it will be fully shown in any case.
