kernelshark: Fix bug with Plot CPU filtering
Plot CPU filtering in kernelshark has the following bug:
1) Deselect CPU A from Plot CPU list
2) Plot gets updated with no CPU A
3) Deselect CPU B
4) Plot continues to have CPU B
This is due to a bug in graph_plot_cpus_update_callback(),
which seems to be checking old_all_cpus != new_all_cpus before doing any
update. This condition is true on 1, but false on 2.
Removing that check fixes the problem.
Tested:
Above sequence now does expected filtering.
