From: Dylan Yudaken <dylany@meta.com>

Subject: Do not always expect multishot recv to stop posting events
Patch-mainline: yes
Git-commit: 0d4fdb416718a70a4a90c5c4722b38cf44849195
References: kernel 6.2
Later kernels can have a fix that does not stop multishot from posting
events, and would just continue in overflow mode.
