To prevent erros from occurring when the src string is longer than the

In kstrdup(), it is critical to ensure that the dest string is always
NUL-terminated. However, potential race condidtion can occur between a
writer and a reader.
Consider the following scenario involving task->comm:
readerwriter
len = strlen(s) + 1;
Let's explicitly ensure the destination string is NUL-terminated. This way,
it won't be affected by changes to the source string.

Is it appropriate for you to apply this to the mm tree?
