    Subject[patch 010/100] tracing/core: fix early free of cpumasks
    -stable review patch.  If anyone has any objections, please let us know.
    ---------------------

    From: Frederic Weisbecker <fweisbec@gmail.com>

    upstream commit: 2fc1dfbe17e7705c55b7a99da995fa565e26f151

    Impact: fix crashes when tracing cpumasks

    While ring-buffer allocation, the cpumasks are allocated too,
    including the tracing cpumask and the per-cpu file mask handler.
    But these cpumasks are freed accidentally just after.
    Fix it.
