Re: [PATCH] xen-blkback: enlarge the array size of blkback name

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. On 2015/3/26 19:23, Roger Pau Monné wrote: El 13/03/15 a les 16.52, Tao Chen ha escrit:

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.
