Subject[PATCH 00/14] [GIT PULL][v2.6.39] tracing/filter: More robust filtering


I finally finished and tested all these patches. Minor fixes were
made since the last email. I also added a couple of patches to
allow a switch between filters instead of having a small period that
the filter would either filter out all or none as it changes the

Please pull the latest tip/perf/filter tree, which can be found at:


Steven Rostedt (14):
tracing/filter: Have no filter return a match
tracing/filter: Move OR and AND logic out of fn() method
tracing/filter: Dynamically allocate preds
tracing/filter: Call synchronize_sched() just once for system filters
tracing/filter: Allocate the preds in an array
tracing/filter: Free pred array on disabling of filter
tracing/filter: Use a tree instead of stack for filter_match_preds()
tracing/filter: Optimize short ciruit check
tracing/filter: Check the created pred tree
tracing/filter: Optimize filter by folding the tree
tracing/filter: Move MAX_FILTER_PRED to local tracing directory
tracing/filter: Increase the max preds to 2^14
tracing/filter: Swap entire filter of events
tracing/filter: Remove synchronize_sched() from __alloc_preds()
