Subject: [PKTGEN]: Remove write-only variable.
X-Git-Tag: v4.13~35755^2
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=88282c6ecf0dacefda6090b0289d35e8a3cc6221;p=mirror_ubuntu-bionic-kernel.git

[PKTGEN]: Remove write-only variable.

The pktgen_thread.pid is set to current->pid and is never used
after this. So remove this at all.

Found during isolating the explicit pid/tgid usage.
