Memory Management is one of the hardest subsystem of the Linux kernel, it
take a few months to even grasp the concept of how it is managed and
converting it into useful code will take longer.
To get a taste of code
http://lxr.free-electrons.com/source/mm/

See, if you can understand what is going on around.

Also recommend to read to x86 memory management techniques and then Bovet
and Cessati's Chapter on Memory management.

Secondly, this list is not a list to find projects for kernel, it is to ask
specific doubts about concepts of kernel development and help in
understanding the code.

The general idea of starting with kernel is writing a small character or
block device driver as concept and writing a report about understanding of
kernel subsystem, it will form a good project. If not, try to fix a small
bug in the kernel. Even fixing a small bug, if you have not initiated
yourself to kernel programming will take time and effort.


Lastly before asking such questions, you should look around for relevant
articles, mailing list and possibly visit stackoverflow, because there must
be someone who has asked a similar question before.


Thanks
