The rationale for this is that since NULL is not guaranteed to be zero
by the C standard, memset() doesn't really initialize pointers properly.
The above does. This came up when I wanted to replace explicit NULL
assignments from the NTFS code with kcalloc() and the maintainer
refused. Al Viro suggested the above form and was accepted by the NTFS
maintainer as well.
