Ftrace supports parallel tracing in isolated ring buffers. Trace-cmd
also supprts this ftrace functionality, it saves the data from all
buffers into single trace.dat file. When such file is opened by
KernelShark, it loads the tracing data only from the top biffer.
Support for loading data from all buffers, located in a single trace.dat
file, is added. Each buffer is loaded as different KernelShark session.

Tzvetomir (VMware)  Stoyanov (5):
  KernelShark: Add stream name
  KernelShark: Fix compilation issues on  Fedora 32
  KernelShark: Fix combo plot plugin crash in case of multiple streams
  KernelShark: Load trace.dat file with ftrace sub-buffers
  KernelShark: New libkshark API for loading all entries from given file
