[PATCH 0/3] Fixes for syzbot problem

[yanjun.zhu@linux.dev]

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.

Zhu Yanjun (3):
  RDMA/rxe: Fix "kernel NULL pointer dereference" error
  RDMA/rxe: Fix the error caused by qp->sk
  RDMA/rxe: Remove the unused variable obj
