Subject: [PATCH] xfs: event tracing support
Subject: xfs: event tracing support
From: Christoph Hellwig <hch@....de>
Convert the old xfs tracing support that could only be used with the out
of tree kdb and xfsidbg patches to use the generic event tracer.
To use it make sure CONFIG_EVENT_TRACING is enabled and then enable all
xfs trace channels by:
echo 1 > /sys/kernel/debug/tracing/events/xfs/enable
Alternatively you can also enable invivididual trace events in XFS or
even filter on them. Take a look at Documentation/trace/events.txt
for details. To reads the events do a
cat /sys/kernel/debug/tracing/trace
which will give output like this:
# tracer: nop
#
# TASK-PID CPU# TIMESTAMP FUNCTION

This patch converts most existing trace points in XFS
more or less fully to the event tracer. Note that the infrastructure
already provides pid value (and theoretically the task name, although that's
buggy currently) so we don't have to record
them ourselves. There also are a couple of places where we provide
information more usefull for general tracing instead of pointers for
gdb, e.g. the inode number instead of the inode pointer address.
A couple of tracers are not converted currently:
- the log grant tracing is gone. There was just one callsite left
with most state changes missing, indicating severe bitrot. I don't
plan to re-introduce it for now.
- the filestreams tracing is left as-is for now. It has some very
funky tracers covering all kinds of special cases. If anyone cares
enough about filestreams they should take a look.
- the btree tracer. Due to the different record/key types we can't
handle it with the current tracing infrastructure. I'm working
with Steve to get some infrastructure to get this back.
All this gives a quite massive patch of:
67 files changed, 1563 insertions(+), 2237 deletions(-)
So while adding actual tracing support without xfsidbg we actually
remove lots of lines of code.

Updates since v1:
- move the TRACE_SYSTEM define out of the include guard
- add a few missing xfs_trace.h inclusions that escaped quilt
- fixed a couple of format string warnings on x86-64, now
also tested on x86-64.
