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:
