The branch stable/13 has been updated by hselasky: URL: https://cgit.FreeBSD.org/src/commit/?id=b7ea0ff6a2d59c10f246fd40a2536bdd2214d0fe commit b7ea0ff6a2d59c10f246fd40a2536bdd2214d0fe Author: Hans Petter Selasky <hselasky@FreeBSD.org> AuthorDate: 2022-02-24 09:59:38 +0000 Commit: Hans Petter Selasky <hselasky@FreeBSD.org> CommitDate: 2022-02-24 09:59:38 +0000 mlx5e: Make TLS tag zones unmanaged These zones are cache zones used to allocate TLS offload contexts from firmware. Releasing items from the cache is a sleepable operation due to the need to await a response from the firmware command freeing the tag, so items cannot be reclaimed from the zone in non-sleepable contexts. Since the cache size is limited by firmware limits, avoid this by setting UMA_ZONE_UNMANAGED to avoid reclamation by uma_timeout() and the low memory handler.
