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.
