Subject[PATCH 0/4] tracing: Updates to dynamic event API
Date
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
