Getting kernel version from linux kernel module at runtime

Question

how can I obtain runtime information about which version of kernel is running from inside linux kernel module code (kernel mode)?

Answer 1

You can only safely build a module for any one kernel version at a time. This means that asking from a module at runtime is redundant.

You can find this out at build time, by looking at the value of UTS_RELEASE in recent kernels this is in amongst other ways of doing this.
