- `dep.c` and `dep2.c`: `debugfs_create_u32` does not return anymore, not sure why: https://unix.stackexchange.com/questions/593983/creating-a-debugfs-file-that-is-used-to-read-write-u32-value/621282#621282 So just doing `debugfs_lookup` for now - vermagic.c:51161bfc66prevents its usage in v5.8. Just migrating to `init_utsname` for now - procfs.c: `struct file_operations` moved to a new `struct proc_ops` at:b567e07513- myprintk.c: `pr_warning` dropped for `pr_warn`:61ff72f401- `poll.c`: `kthread_func` is not defined in kernel, prefix with lkmc to avoid conflict Fix https://github.com/cirosantilli/linux-kernel-module-cheat/issues/136 Fix https://github.com/cirosantilli/linux-kernel-module-cheat/issues/137
