enter image description hereI’ve been working on customizing the Linux kernel, specifically in the networking stack. I modified the tcp_sendmsg_locked function to include a mod_timer call, aiming to delay the tcp_push. However, after making these changes, I’m encountering a kernel panic when running netperf to measure throughput.

I have Linux 3.10.65 armv7l kernel on my industrial computer, need to upgrade it manually is it possible if it is, how?
