Hi all,

Commit 20401d1058f3f841f35a594ac2fc1293710e55b9("ipc: replace costly bailout check in sysvipc_find_ipc()" fixes a high cve and optimizes the costly loop by adding a checkpoint, which I think might be a good candidate for the stable branches

What do you mean by "high cve"?

And that feels like it's an artificial benchmark fixup, what real workload benefits from this change?

thanks,
