Sharing a buffer amoung several precompiled scripts
This patch adds the relay channel sharing feature against systemtap-20070512.
With this patch, you can share one relay channel among several pre-compiled
scripts.
To run a host script which provides interfaces of relay channel:
stap -b -DRELAY_HOST host.stp
To add some guest script:
stap -DRELAY_GUEST guest1.stp
stap -DRELAY_GUEST guest2.stp
This patch is just a minimum implementation. So you can NOT run several host
scripts concurrently.
I'd like to support custom applications which consist of a group of
pre-compiled scripts and share an one huge buffer among them.
I think this kind of custom application is useful for recording detailed events
of servers which don't have any debuginfo and compiling environment by
themselves.
