I am not maintainer for this code, and also wangjingyu beat you to this
one.  But one question:  Given that this patch would cause "git blame"
to list you as the immediate point of contact for each line changed,
are you ready to answer all questions about each of those lines of code?
For example, given C's default initialization to zero, why is the "mm"
field explicitly set to NULL?

						Thanx, Paul
