Re: How to install kernel modules after a successful compiling

[FuLong Wang <fulwang@linux.vnet.ibm.com>]

When I try to install the new built kernel and modules, i found the 
install script will assign the kernel version as "3.10.0".

Where is this defined?
Can we keep it as the current kernel version or change it as we want?
