Subject: [PATCH 5.7 305/477] rxrpc: Adjust /proc/net/rxrpc/calls to display call->debug_id not user_ID
From: David Howells <dhowells@...hat.com>
[ Upstream commit 32f71aa497cfb23d37149c2ef16ad71fce2e45e2 ]
The user ID value isn't actually much use - and leaks a kernel pointer or a
userspace value - so replace it with the call debug ID, which appears in trace
points.
