Smile Kernel Version Numbering


Am a linux user from last few years,but still confused on kernel version numbering.
eg:2.6.32.21
somewhere i saw 2=major num,6=minor number.On anoyher place its 6=major number,32=minor number.

Plz give a clear solution for this.
i have seen even releases are stable.and odd releases are for development.
Plz provide a clarification for this too

Hi,

Maybe this will clear things up a bit: Linux kernel - Version numbering

Hope this helps.

The link is very useful.It explains about version clearly.
plz checkout the following.


http://www2.essex.ac.uk/cs/services/...el-version.htm
http://www.linuxcertified.com/e-lear.../html/1_9.html
http://book.opensourceproject.org.cn...6lev1sec4.html

These are making me confused.

Which to believe

Hi,

All basically say the same: major number + minor number + Revision Number/Micro number (+ Patch level)

2.6.32.21 would be:
Major -> 2
Minor -> 6
Micro -> 32
Patch level -> 21

The last 2 (micro + patch) is sometimes revered to as Revision (-> 32.21)

Hope this helps.

When in doubt consult the (kernel) source tree. There is a README at the top level; then look in ../Documentation
applying-patches.txt is recommended reading.
