hi,
i found this structure is defined in mm/vmalloc.c :
"static struct vm_struct * vmlist = NULL;"
it appears that vmlist be initiated as null. but in function
get_vm_area(), which is called by kmalloc(), it doesn't work if vmlist is
null. so i think vmlist must be initiated somewhere else. but where? thx
regards,
Wang

Hi Wang,
There's only 3 lines that reference it in vmalloc.c, so it
shouldn't be too hard to figure out, no?
Neil.
