Not sure why a so recent commit is not in linux-next, maybe one needs to fetch tags or something. Fetching git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next-history.git helped me to get this commit: $ git show d4104460aec1 commit d4104460aec152e23cf80ab1f950f414bf94f4ea (HEAD, tag: next-20190211) Author: Stephen Rothwell Date: Mon Feb 11 18:37:26 2019 +1100 Add linux-next specific files for 20190211
