SubjectRe: [PATCH v9 3.2 7/9] tracing: uprobes trace_event interface

btw., i'd write the CONFIG_UPROBE_EVENT .config help text:

This allows the user to add tracing events on top of userspace
dynamic events (similar to tracepoints) on the fly via the
traceevents interface. Those events can be inserted wherever
uprobes can probe, and record various registers.

This option is required if you plan to use perf-probe
subcommand of perf tools on user space applications.

In a clearer form:

This allows the user to add user-space dynamic events on the
fly, similar to tracepoints. These events can be inserted
into just about any user-space code transparently, and can
record register state there on the fly, which is then used by
instrumentation tools.

This option is required if you plan to use the "perf probe"
subcommand of the perf tool on user space applications.

Thanks,

Ingo
