Subject: [PATCH bpf-next 07/10] s390/bpf: Enable arena
Date: Thu, 27 Jun 2024 11:07:10 +0200	[thread overview]
Message-ID: <20240627090900.20017-8-iii@linux.ibm.com> (raw)
In-Reply-To: <20240627090900.20017-1-iii@linux.ibm.com>

Now that BPF_PROBE_MEM32 and address space cast instructions are
implemented, tell the verifier that the JIT supports arena.
