+Subject: [PATCH 1/2] Use proc_ops structure for kernel version >= 5.6.0
+
+Since 5.6.0, proc_create requires a `struct proc_ops *` argument instead
+of `struct file_operations *`.
+Commit with the migration in the kernel source can be found at
+https://github.com/torvalds/linux/commit/d56c0d45f0e27f814e87a1676b6bdccccbc252e9
