Subject: [RFC PATCH v10 00/50] perf tools: filtering events using eBPF programs
This is the 10th version which tries to introduce eBPF programs to perf.
Compare with v9 there are only some small changes:
1. Squash patch 2/50 and 3/50 in v9 together, never check host
include/linux/bpf.h, so bpf feature check will always green.
2. Fix compiling error when CONFIG_BPF_SYSCALL is set but
CONFIG_BPF_EVENT is unset. See patch 1/50.
3. In add_perf_probe_events(), always init kernel symbol maps.
He Kuang (3):
perf tools: Move linux/filter.h to tools/include
perf tools: Introduce arch_get_reg_info() for x86
perf record: Support custom vmlinux path
