tracing/filters: allow user input integer to be oct or hex
Before patch:
# echo 'parent_pid == 0x10' > events/sched/sched_process_fork/filter
# cat sched/sched_process_fork/filter
parent_pid == 0
After patch:
# cat sched/sched_process_fork/filter
parent_pid == 16
Also check the input more strictly.
