Thanks for your patch!
I have tested the above patch on top of v6.3-rc4 kernel.
This issue was fixed.
Reproduced code from syzkaller: https://github.com/xupengfe/syzkaller_logs/blob/main/230327_041425_io_poll_remove_entries/repro.c
One more info, bisect methodology comes from myself, not from syzkaller.
Thanks!
BR.
