Subject: tracing: Increase tracing map KEYS_MAX size
Git-repo: git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git
Git-commit: b6bfbfc6aa974b01b2b28a4b354e5626811e9d28
Patch-mainline: Queued in subsystem maintainer repository
References: SLE Realtime Extension

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.
