I've applied this patch on top of Arch Linux's 6.12.8-arch1-1 kernel,
and the reproducer [1] has not triggered a infinite loop / network
freeze yet in ~1h, whereas on unmodified 6.12.8-arch1-1 it usually
triggers one in 5-10min, hence:
Tested-by: Friedrich Weber <f.weber@...xmox.com>
If necessary, I can rerun the test on a mainline kernel.
Thank you for the quick fix!
