Subject[PATCH 0/10] ftrace/filter: Trace events filtering related fixies
Date
hi,

on the way to perf/ftrace filtering changes, I made some changes
to the current events filtering code. It could be divided into 3
parts roughly:

- remove unnecessary dynamic allocations (patches 1 - 4)
- unify the predicate tree walking (patches 5 - 9)
- added startup test for event filtering (patch 10)

attached patches:
- 01/10 tracing/filter: Use static allocation for filter predicates
- 02/10 tracing/filter: Separate predicate init and filter addition
- 03/10 tracing/filter: Remove field_name from filter_pred struct
- 04/10 tracing/filter: Simplify tracepoint event lookup
- 05/10 tracing/filter: Unify predicate tree walking, change check_pred_tree function to use it
- 06/10 tracing/filter: Change count_leafs function to use walk_pred_tree
- 07/10 tracing/filter: Change fold_pred_tree function to use walk_pred_tree
- 08/10 tracing/filter: Change fold_pred function to use walk_pred_tree
- 09/10 tracing/filter: Change filter_match_preds function to use walk_pred_tree
- 10/10 tracing/filter: Add startup tests for events filter

wbr,
jirka
