linux.git/tools/testing/selftests/bpf/default.profraw, branch v7.2-rc2 Linux kernel source tree selftests/bpf: Add buddy allocator for libarena 2026-04-27T01:12:22+00:00 Emil Tsalapatis emil@etsalapatis.com 2026-04-26T19:03:36+00:00 86426a28c52d756a5edbe29885716128b8915991 Add a byte-oriented buddy allocator for libarena. The buddy allocator provides an alloc/free interface for small arena allocations ranging from 16 bytes to 512 KiB. Lower allocations values are rounded up to 16 bytes. The buddy allocator does not handle larger allocations that can instead use the existing bpf_arena_{alloc, free}_pages() kfunc.
