Hi Jose,
I'm going to mark this patch series as 'Changes Requested' since it depends on
Sakari's subnotifier work. Once that is accepted I assume you'll make a v9 on

Return errors, because the operation may fail.

load_misc_binary() makes a local copy of fmt->interpreter under entries_lock
to avoid the race with kill_node() but this is not enough; the whole Node

The current logic looks wrong in any case, once we close interp_file
it doesn't make any sense to delay kfree(inode->i_private), this Node
is no longer valid. Even if the MISC_FMT_OPEN_FILE/interp_fi

Setting up groups can be complicated due to the complicated scheduling
restrictions of different PMUs.
User tools usually don't understand all these restrictions.
Still in many cases it is useful to set up groups and they work most of
the time. However if the group is set up wr

Add code to perf list to print metric groups, and metrics
that don't have an event name. The metricgroup code collects
the eventgroups and events into a rblist, and then prints
them according to the configured filters.
The metricgroups are printed by default, but can be

Some of the metrics formulas (like GFLOPs) need to know how long the

which reports time in second. It maps to the dummy event, but is special

Some perf stat metrics use an internal "duration_time" metric. It is not
correctly printed however. So hide it during output to avoid confusing
