Fixing this is easy with b4 [0] (the recommended way of sending patches to mm): $ b4 prep --auto-to-cc Alternatively, you can use scripts/get_maintainer.pl: $ scripts/get_maintainer.pl --nogit-fallback [0]: https://b4.docs.kernel.org/en/latest/contributor/send.html Specifically, the following appear to be missing: david@kernel.org liam@infradead.org mhocko@suse.com rppt@kernel.org surenb@google.com vbabka@kernel.org > > Thanks, > Park Tae-sun -- Cheers, Lorenzo
