Keep libarenaself-contained by moving all functionality into its include/directory. Also add libarena/include to the standard includepaths for the selftests to make the moved headers easy toaccess by existing selftests.Some functionality is required by libarena but not strictlyarena-related. We still move it to the libarena/include path,which is an upgrade from directly accessing them from theselftests/bpf directory using relative paths.A new bpf_may_goto.h file is split off of bpf_experimental.h.bpf_arena_spin_lock.h and bpf_arena_common.h are moved tolibarena/include. bpf_atomic.h is also moved to libarenabecause it is necessary for arena spinlocks.For bpf_arena_spin_lock.h, mark the spinlock state array as __weakto define the spinlock state array in the header while alsobeing compatible with multi-compilation unit programs. Whilewe're at it, we remove unnecessary definitions from existingtest programs.Signed-off-by: Emil Tsalapatis <emil@etsalapatis.com>Link: https://lore.kernel.org/r/20260426190338.4615-4-emil@etsalapatis.comSigned-off-by: Alexei Starovoitov <ast@kernel.org> List of files: /linux/tools/testing/selftests/bpf/libarena/include/bpf_atomic.h Sun, 26 Apr 2026 21:03:33 +0200 Emil Tsalapatis <emil@etsalapatis.com>
