Eric Dumazet dbca1596bb ping: convert to RCU lookups, get rid of rwlock 
Using rwlock in networking code is extremely risky.
writers can starve if enough readers are constantly
grabing the rwlock.

I thought rwlock were at fault and sent this patch:

https://lkml.org/lkml/2022/6/17/272

But Peter and Linus essentially told me rwlock had to be unfair.

We need to get rid of rwlock in networking code.

Fixes: c319b4d76b ("net: ipv4: add IPPROTO_ICMP socket kind")
