Subject: [PATCH 0/3] tracing: add support for multibuffer event filters

The three patches in this patchset are essentially the same patches
that have already been reviewed as part of the trace-event-triggers
patchset, but are separated out because they're actually completely
independent of that patchset and could presumably go into tracing-next
at this point.

In the original patchset, these patches came later in the series;
moving them up I had to fix up a few conflicts and assumptions from
their position in the previous patchset.  The only real difference is
that for patch 1 I added TRACE_EVENT_FL_USE_CALL_FILTER to the flags,
which patch 3 removes since it adds trace_event_files for syscalls.

Basically when ftrace multibuffer support was added, the event filters
were neglected and this patchset fixes that.  Also when soft-disable
was added, it didn't cover syscalls - this adds that and in the
process by virtue of using ftrace_event_files, also enables
multibuffer event filter support for syscalls as a nice side effect.

The following changes since commit 29ad23b00474c34e3b5040dda508c78d33a1a3eb:

  ftrace: Add set_graph_notrace filter (2013-10-18 22:23:16 -0400)
