Subject: [PATCH 1/3] net: Remove task_struct::bpf_net_context init on fork.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.10/older/patches-6.10.2-rt14.tar.xz
There is no clone() invocation within a bpf_net_ctx_…() block. Therefore
the task_struct::bpf_net_context has always to be NULL and an explicit
initialisation is not required.
Remove the NULL assignment in the clone() path.
