I'm not running Ubuntu, I'm looking at the 3.16.4-based kernel source in our local LXR database reportedly from the Ubuntu 14.10 linux-source package. IIRC, I ran 'make modules_prepare' using the 14.10 kernel config file which is supposed to generate the appropriate header files necessary for compiling out-of-tree drivers, but the only thing in ./include/generated/utsrelease.h is: #define UTS_RELEASE "3.16.4" How is it the stuff in /usr/src/linux-headers-`uname -r`/include/generated/utsrelease.h is different? Is it generated from a different config file or build scripts? > > 39 is the ABI number, which is essentially the number of the release of > that series (3.13.0) of kernel.
