Subject[PATCH 10/40] staging/lustre/server: use unified request handler for MGS
Date
From: Mikhail Pershin <tappro@whamcloud.com>

- Unify request handler. It finds target for particular request and
calls appropriate handler for it. Generic handlers are moved to
the unified target code. The tgt_session_info is introduced to
store all request-related data and passed to all handlers.
- Pack reply in llog server functions early and use err_serious()
- remove obsoleted llog_origin_handle_cancel(), it is not used
anymore
- remove push_ctxt/pop_ctxt from llog server function, it is based
on OSD now.
