Now that there's pretty much a one to one mapping between the struct event_trigger_ops and struct event_command, there's no reason to have two different structures. Merge the function pointers of event_trigger_ops into event_command. There's one exception in trace_events_hist.c for the event_hist_trigger_named_ops. This has special logic for the init and free function pointers for "named histograms". In this case, allocate the cmd_ops of the event_trigger_data and set it to the proper init and free functions, which are used to initialize and free the event_trigger_data respectively. Have the free function and the init function (on failure) free the cmd_ops of the data element.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
