Subject: Files in include/trace/events

Hi Chuck,

I was just looking over some files in include/trace/events/ and noticed
that there's sunrpc_base.h, fs.h and nfs.h that are not event files.

The include/trace/events/ directory should only hold files that are to
create events, not headers that hold helper functions.

Can you please move them out of include/trace/events/ as that directory
is "special" in the creation of events.

Perhaps we could create a new directory include/linux/trace/ or
include/trace/linux/ specific for these types of files?

Thanks!

-- Steve

Hi Vlastimil,

I also noticed that mmflags.h is in that directory too.

I'd like to keep only headers defining TRACE_EVENT() in that directory,
as files there have special meaning.

Thanks,

I can take responsibility for moving the helper files I created.
IIRC there are a few from the RDMA core subsystem as well.

But let's first decide on a proper destination for such files.
A sister directory to include/trace/events, like

include/trace/ < something >

makes sense to me.

I guess we could move that one to e.g. mm/mmflags.h as it's used also
outside of trace events anyway (mm/debug.c), but it's not something to
expose to general use in include/ But most includes are from proper
include/trace/events/*.h headers so dunno, maybe
include/trace/<something>/mmflags.h would be more appropriate.
