From: Zhu Yanjun <yanjun.zhu@linux.dev> In the link: https://syzkaller.appspot.com/bug?id=3efca8275142fbfdde6cf77e1b18b1d5c6794d76 a rxe problem occurred. I tried to reproduce this problem in local hosts. Finally I could reproduce this problem in local hosts. The commit ("RDMA/rxe: Fix "kernel NULL pointer dereference" error") tries to fix this problem. After this syzbot problem disappeared, another problem appeared when qp->sk failed to initialized. The commit ("RDMA/rxe: Fix the error caused by qp->sk") tries to solve this problem. When I delved into the source code to solve the above problems, I found that the member variable obj in struct rxe_task is not needed. So the commit ("RDMA/rxe: Remove the unused variable obj") removes this variable obj. After the 3 commits, in locat hosts, the whole system can work well.
