[Samba] how to use the *.patch file

[Ä£¶h]

hi,
may i ask some stupid question.  :)
I am using Samba 2.2.8a, how should i do if i don't want upgrade to the =
latest version of Samba but use the *.patch file?

And there are so many patch files, should i patch every file to my =
system?

If the affected release of a patch file is "3.0.x <=3D 3.0.6", dose it =
mean this security issue just affect version 3.0.x and my system can =
ignore this?
