removing the static keyword of "head" to fix this.
This should be "Remove the static..." as noted in the kernel documentation:
"Describe your changes in imperative mood, e.g. “make xyzzy do frotz” instead of “[This patch] makes xyzzy do frotz” or “[I] changed xyzzy to do frotz”, as if you are giving orders to the codebase to change its behaviour."
Please have a look on this page here: https://www.kernel.org/doc/html/latest/process/submitting-patches.html
