I guess it is pathname, based on ignore_list file [1] of stable-queue repo.

https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/tree/ignore_list#n16
Oh, that's a bit sad.
- other trees sometimes mess with mm/ and they probably aren't aware
that they need an explicit cc:stable.
- misses drivers/block/zram and probably various other things that
the MM team maintains.
Oh well, I guess simple mm/* coverage is good enough. But I do worry a
little that useful fixes coming into mm/ via other trees without
cc:stable will get missed.
How should we improve the filter? mm/ AND signed off by akpm?
