uname command manual page show about these options as follow:
 -r, --kernel-release
              print the kernel release

        -v, --kernel-version
              print the kernel version

but i found that these options are conflicting as given in manual page

eg

inlc7940> uname -v
#1 SMP Wed Dec 2 12:27:56 UTC 2009
inlc7940> uname -r
2.6.16.60-0.58.1.3835.0.PTF.638363-smp

Help me to solve this problem....
