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
