register/unregister_ftrace_command() are only ever called from __init
functions, so can themselves be made __init.
Also make register_snapshot_cmd() __init for the same reason.

Hi,
This is v9 of the trace event triggers patchset. This version
addresses the comments and feedback from Steve Rostedt on v8.
v9:
- changed the comments in ftrace_syscall_enter/exit to reflect that
the tracepoint handlers are inside rcu_read_lock_sched() rather
than just
Provide a basic overview of trace event triggers and document the
available trigger commands, along with a few simple examples.

The original SOFT_DISABLE patches didn't add support for soft disable
of syscall events; this adds it and paves the way for future patches
allowing triggers to be added to syscall events, since triggers are
built on top of SOFT_DISABLE.

Add 'enable_event' and 'disable_event' event_command commands.
enable_event and disable_event event triggers are added by the user
via these commands in a similar way and using practically the same
syntax as the analagous 'enable_event' and 'disable_event' ftrace
function commands, but instead of

the user via this command in a similar way and using practically the

instead of writing to the set_ftrace_filter file, the snapshot event
trigger is written to
Add a generic event_command.set_trigger_filter() op implementation and
have the current set of trigger commands use it - this essentially
gives them all support for filters.
Syntactically, filters are supported by adding 'if filter' just
after the command, in which case only events matching the
The trace event filters are still tied to event calls rather than
event files, which means you don't get what you'd expect when using
filters in the multibuffer case:
Before:

by the user via this command in a similar way and using practically

but instead of writing to the set_ftrace_filter file, the stacktrace

Add a 'trigger' file for each trace event, enabling 'trace event
