While I understand that the linux kernel has to use a special modified version of zlib, it is out of date and recently Mark Adler fixed some possible loss of data and data corruption (according to the C standard) so as such I think it is important to update the zlib on the linux mainline kernel to be more safe than sorry later. zlib is also on github as well. See the commit history of https://github.com/madler/zlib for more information. The files I noticed are in need of the update are in the lib subfolder on the root of the github repository. https://github.com/torvalds/linux/tree/master/lib/. Let me know if you guys agree to my idea of updating zlib on the linux kernel.
