[PATCH 07/15] tracing: change CPU ring buffer state …
https://lkml.iu.edu/hypermail/linux/kernel/1205.2/01622.html
tracing_cpumask: This is a mask that lets the user only trace on specified CPUS. The format is a hex string representing the CPUS. The tracing_cpumask currently doesn't affect the tracing state of per-CPU ring buffers. This patch enables/disables CPU recording as its corresponding bit in tracing_cpumask is set/unset.
