Hi there,

My name is Shaobo He and I am a graduate student at University of Utah. 
I am using a static analysis tool to search for null pointer 
dereferences and came across a couple of potentially invalid memory 
accesses in the file drivers/block/drbd/drbd_worker.c: in function 
`drbd_start_resync`, pointer variable `connection` in line 1727 can be 
NULL while is dereferenced at line 1767 (```if (current == 
connection->worker.task) {```).

Please let me know if it makes sense. I am looking forward to your
