[PATCH] rtla: Fix build without libbpf header
From: Tomas Glozar
Date: Mon Mar 30 2026 - 05:12:45 EST
rtla supports building without libbpf. However, BPF actions
patchset [1] adds an include of bpf/libbpf.h into timerlat_bpf.h,
which breaks build on systems that don't have libbpf headers
installed.
This is a leftover from a draft version of the patchset where
timerlat_bpf_set_action() (which takes a struct bpf_program * argument)
was defined in the header. timerlat_bpf.c already includes bpf/libbpf.h
via timerlat.skel.h when libbpf is present.
Remove the redundant include to fix build on systems without libbpf
headers.
