The Linux kernel 2.6.15 is released yesterday.
In this version of the kernel there are 889 files added (472073 lines of code), 512 deleted (325233 lines of code) and 6327 changed.

Note: In the 2.6 kernel it is generally preferred to build the kernel with CONFIG_KALLSYMS so that it produces readable dumps that can be used as-is (this also produces better output than ksymoops).

You can get the patch or the full release from here:
