Subject: [PATCH 0/2] powerpc/bpf: Fix issue with atomic ops
Date: Thu, 1 Jul 2021 20:38:57 +0530 [thread overview]
Message-ID: <cover.1625145429.git.naveen.n.rao@linux.vnet.ibm.com> (raw)
The first patch fixes an issue that causes a soft lockup on ppc64 with
the BPF_ATOMIC bounds propagation verifier test. The second one updates
ppc32 JIT to reject atomic operations properly.
