eprobes: Remove redundant event type information

Currently, the event probes save the type of the event they are attached
to when recording the event. For example:

# echo 'e:switch sched/sched_sw

eprobes: Remove redundant event type information

Currently, the event probes save the type of the event they are attached
to when recording the event. For example:

# echo 'e:switch sched/sched_switch prev_state=$prev_state prev_prio=$prev_prio next_pid=$next_pid next_prio=$next_prio' > dynamic_events
# cat events/eprobes/switch/format

name: switch
ID: 1717
format:
field:unsigned short common_type; offset:0; size:2; signed:0;
field:unsigned char common_flags; offset:2; size:1; signed:0;
field:unsigned char common_preempt_count; offset:3; size:1; signed:0;
field:int common_pid; offset:4; size:4; signed:1;

field:unsigned int __probe_type; offset:8; size:4; signed:0;
field:u64 prev_state; offset:12; size:8; signed:0;
field:u64 prev_prio; offset:20; size:8; signed:0;
field:u64 next_pid; offset:28; size:8; signed:0;
field:u64 next_prio; offset:36; size:8; signed:0;

print fmt: "(%u) prev_state=0x%Lx prev_prio=0x%Lx next_pid=0x%Lx next_prio=0x%Lx", REC->__probe_type, REC->prev_state, REC->prev_prio, REC->next_pid, REC->next_prio

The __probe_type adds 4 bytes to every event.

One of the reasons for creating eprobes is to limit what is traced in an
event to be able to limit what is written into the ring buffer. Having
this redundant 4 bytes to every event takes away from this.

The event that is recorded can be retrieved from the event probe itself,
that is available when the trace is happening. For user space tools, it
could simply read the dynamic_event file to find the event they are for.
So there is really no reason to write this information into the ring
buffer for every event.

tracing: Remove size restriction on tracing_log_err cmd strings

Currently, tracing_log_err.cmd strings are restricted to a length of
MAX_FILTER_STR_VAL (256), which is too short for some commands already
seen in the wild (with cmd strings longer than that showing up
truncated).

Remove the restriction so that no command string is ever truncated.

Merge tag 'trace-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace

Pull tracing updates from Steven Rostedt:
"New:

- The Real Time Linux Analysis (RTLA) tool is added to the tools
directory.

- Can safely filter on user space pointers with: field.ustring ~
"match-string"

- eprobes can now be filtered like any other event.

- trace_marker(_raw) now uses stream_open() to allow multiple threads
to safely write to it. Note, this could possibly break existing
user space, but we will not know until we hear about it, and then
can revert the change if need be.

- New field in events to display when bottom halfs are disabled.

- Sorting of the ftrace functions are now done at compile time
instead of at bootup.

Infrastructure changes to support future efforts:

- Added __rel_loc type for trace events. Similar to __data_loc but
the offset to the dynamic data is based off of the location of the
descriptor and not the beginning of the event. Needed for user
defined events.

- Some simplification of event trigger code.

- Make synthetic events process its callback better to not hinder
other event callbacks that are registered. Needed for user defined
events.

And other small fixes and cleanups"

tracing: Add helper functions to simplify event_command.parse() callback handling

The event_command.parse() callback is responsible for parsing and
registering triggers. The existing command implementions for this
callback duplicate a lot of the same code, so to clean up and
consolidate those implementations, introduce a handful of helper
functions for implementors to use.

This also makes it easier for new commands to be implemented and
allows them to focus more on the customizations they provide rather
than obscuring and complicating it with boilerplate code.
