This set includes Peter's work to merge multiple trees for different types of dynamic kallsyms (BPF, ftrace, etc.). Symbols for BPF programs are migrated to use kallsym_tree.
I have made minor changes to Peter's patches, and tested them with BPF programs and perf utility. Thanks, Song Peter Zijlstra (3): rbtree_latch: Introduce latch_tree_first() and latch_tree_next() kallsyms: Introduce kallsym_tree for dynamic symbols bpf: migrate symbols for BPF programs to kallsym_tree include/linux/bpf.h | 7 +- include/linux/filter.h | 42 -------- include/linux/kallsyms.h | 16 +++ include/linux/rbtree_latch.h | 54 ++++++++++ kernel/bpf/core.c | 167 ++++------------------------- kernel/events/core.c | 35 ------ kernel/extable.c | 6 +- kernel/kallsyms.c | 201 ++++++++++++++++++++++++++++++++--- 8 files changed, 281 insertions(+), 247 deletions(-) -- 2.17.1
