Should this be?:
offset = (unsigned long)vma->vm_private_data;
offset is an unsigned long, not a pointer. ->vm_private_data is a
void pointer.
It causes a GCC warning:
mm/shmem.c: In function ‘shmem_interleave’:
mm/shmem.c:1341:9: warning: assignment makes integer from pointer without a cast [enabled by default]
