Hi Steve,
This implements my fix to restore single input filtering behavior
(bz217038) and adds support for global filters, as you requested.
On another topic, a current behavior that seems weird in my opinion is
that the following negates the second filter as well.
"trace-cmd -i trace.dat.1 -v -F tp1 -i trace.dat.2 -F tp2"
I'd prefer that -v would apply only to the following -F. It'd allow me
to do:
"trace-cmd -v -F 'mm_page_alloc' -i trace.dat.1 -i trace.dat.2 ... \
-i trace.dat.10 -F 'mm_page_alloc:order==1'"
It obviously breaks the interface, so I didn't implement it here. Would
like to hear your input, though. We could have a new syntax:
"trace-cmd ! -F tp1 -F tp2 ! -F tp3"
Thanks,
