From: Tom Zanussi Date: Fri, 22 Sep 2017 14:58:19 -0500 Subject: [PATCH 05/42] tracing: Increase tracing map KEYS_MAX size Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.14/older/patches-4.14.15-rt11.tar.xz The current default for the number of subkeys in a compound key is 2, which is too restrictive. Increase it to a more realistic value of 3.
