[Cbe-oss-dev] [PATCH 1/4] powerpc/spufs: sputrace: only enable logging on open(), prevent multiple openers

[Jeremy Kerr]

Hi Christoph,

> Did you talk to the PDT people about this?

No, but I'll only merge this patch with approval from the PDT team. Will 
chase this up during the week.

At the moment, we lose these samples anyway, as we reset sputrace_head 
and sputrace_tail on open().

Cheers,


Jeremy
