Subject: [PATCH 0/9] perf sched replay: Make some improvements and fixes

Hi,
  Found some functions to improve and bugs to fix in perf sched replay.

Yunlong Song (9):
  perf sched replay: Use struct task_desc instead of struct task_task
    for     correct meaning
  perf sched replay: Increase the MAX_PID value to fix assertion failure
        problem
  perf sched replay: Alloc the memory of pid_to_task dynamically to
    adapt     to the unexpected change of pid_max
  perf sched replay: Realloc the memory of pid_to_task stepwise to adapt
        to the different pid_max configurations
  perf sched replay: Fix the segmentation fault problem caused by pr_err
        in threads
  perf sched replay: Handle the dead halt of sem_wait when
    create_tasks()     fails for any task
  perf sched replay: Fix the EMFILE error caused by the limitation of
    the     maximum open files
  perf sched replay: Support using -f to override perf.data file
    ownership
  perf sched replay: Use replay_repeat to calculate the runavg of cpu   
     usage instead of the default value 10
