Sorry if this is not relevant to kernel. But since I am patching the kernel - Please consider this as a uber beginner question to ask on this mailing list - forgive me for that.
Now my question is -
What "@@ -321,7 +321,8 @@" mean in this snippet from the patch -
The first number -321 means the line number of the original file that the change takes place. The next number & means that before the change, there were 7 lines of code. The next number +321 is the line number after the change. Since this is the first (and only change) it is the same as the first number. If there multiple changes in a patch, this number can differ greatly from the first number. The last number is the lines of code after the change.
