Subject: [PATCH bpf-next 0/3] capture integers in BTF type info for map defs
Date: Wed, 26 Jun 2019 16:21:30 -0700 [thread overview]
Message-ID: <20190626232133.3800637-1-andriin@fb.com> (raw)
This patch set implements an update to how BTF-defined maps are specified. The
change is in how integer attributes, e.g., type, max_entries, map_flags, are
specified: now they are captured as part of map definition struct's BTF type
information (using array dimension), eliminating the need for compile-time
data initialization and keeping all the metadata in one place.
All existing selftests that were using BTF-defined maps are updated, along
with some other selftests, that were switched to new syntax.
Andrii Nakryiko (3):
libbpf: capture value in BTF type info for BTF-defined map defs
selftests/bpf: convert selftests using BTF-defined maps to new syntax
selftests/bpf: convert legacy BPF maps to BTF-defined ones
