Execute the command modinfo <kernel_module_name> and look for vermagic

shw@shw:/tmp # modinfo btrfs

With uname. See man uname for help

uname -ar 

give you the version of kernel and other info, like this:

Linux ArcherPucci 4.7.2-1-ARCH #1 SMP PREEMPT Sat Aug 20 23:02:56 CEST 2016 x86_64 GNU/Linux

-a give you all info

-r give you kernel version
