[PATCH RFC] staging: lustre: libcfs: tracepoint implementation

From: James Simmons
Date: Sat Aug 19 2017 - 22:49:07 EST

Next message: James Simmons: "Re: [PATCH] staging: lustre: fix structure size for ARM OABI"
Previous message: James Simmons: "[PATCH 00/64 v2] staging: lustre: uapi: normalize the lustre headers"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

The other eye sore for lustre after the UAPI mess is the loony
debugging system. This debugging system was written long before
trace point existed. Well it shows and todays trace point has
surpassed lustre debugging system.

Some of the things implemented are:

1) trace events have a specific naming scheme to allow advance
filter. With this layout you can still use the libcfs module
parameters debugging options to enable classes of trace
events enabled at module startup. This allows debugging for
those special cases.

2) trace events are ratelimited. Its very easy to have 20000
lustre clients over whelm the logging servers. The lustre
debugging code was ratelimited for each debugging statement
which is over kill. For ratelimited trace events its per
subsystem.

3) As each subsystem gets moved over to trace events the native
lustre debugging no longer prints to the console. Currently
I unroll to have trace_event(); pr_info(). Prehaps its could
be rolled into the trace_event macro to make it cleaner.
