tools/bpf: Rename 'struct event' to avoid naming conflict On ppc64le, trying to build bpf seltests throws the below warning: In file included from runqslower.bpf.c:5: ./runqslower.h:7:8: error: redefinition of 'event' struct event { ^ /home/naveen/linux/tools/testing/selftests/bpf/tools/build/runqslower/vmlinux.h:156602:8: note: previous definition is here struct event { ^ This happens since 'struct event' is defined in drivers/net/ethernet/alteon/acenic.h . Rename the one in runqslower to a more appropriate 'runq_event' to avoid the naming conflict. Signed-off-by: Naveen N.

tools/bpf: Add runqslower tool to tools/bpf Convert one of BCC tools (runqslower [0]) to BPF CO-RE + libbpf. It matches its BCC-based counterpart 1-to-1, supporting all the same parameters and functionality. runqslower tool utilizes BPF skeleton, auto-generated from BPF object file, as well as memory-mapped interface to global (read-only, in this case) data. Its Makefile also ensures auto-generation of "relocatable" vmlinux.h, which is necessary for BTF-typed raw tracepoints with direct memory access.
