Subject: [PATCH v2 0/2] bpf: fix reuse of DEVMAP
Date: Wed, 13 Aug 2025 22:09:09 +0200 [thread overview]
Message-ID: <20250813200912.3523279-1-yuka@yuka.dev> (raw)
This patch series includes the previous fix to libbpf for re-using DEVMAP
maps, but modifies it to preserve compatibility with older kernels, thanks
to the feedback given by Martin KaFai Lau.
Additionally adds a basic selftest covering the re-use of DEVMAP maps, as
requested by Eduard Zingerman.
