Hi Steve,
This patchset adds some updates to the 'tracing: Add support for
in-kernel dynamic event API', on top of ftrace/core, addressing the
comments from v4 of that:
- Consolidate the very similar functions
synth_event_add_val/next_val() and inline find_synth_field(), as
suggested by Steve
- Replace the command-building code in dynevent_cmd with equivalent
seq_buf functionality, as suggested by Steve
- Move the check_arg callbacks from the arg objects and explicitly
pass them to the add functions, as suggested by Masami
- Get rid of a useless bit of code in dynevent_add_arg_pair() as
suggested by Masami
With these changes the dynamic event test modules work fine and the
trigger selftests all pass.
Thanks,
Tom
