Subject: net: Remove task_struct::bpf_net_context init on fork.
X-Git-Tag: v6.11-rc1~163^2~105^2~2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2896624be30b049601ec3ef9b08df184d0c70495;p=thirdparty%2Fkernel%2Flinux.git

net: Remove task_struct::bpf_net_context init on fork.

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.
