Hi Kernel hackers,

I have a proposal for an improvement of the CMA allocator (just about 5 
lines of code to make it more robust). I would like to send it to
the linux-mm mailing list (linux-mm at kvack.org according to MAINTAINERS),
but it seems to be inactive. What is the best way to reach the
maintainer of mm/cma.c ?

$ ./scripts/get_maintainer.pl --file mm/cma.c
