Julia Lawall 7ca5ca60cb fs/autofs4: use memdup_user 
Use memdup_user when user data is immediately copied into the allocated
region.  Elimination of the variable ads, which is no longer useful.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>

expression from,to,size,flag;
position p;
identifier l1,l2;
@@

-  to = \(kmalloc@p\|kzalloc@p\)(size,flag);
+  to = memdup_user(from,size);
   if (
