determine a linux kernel version of a patch file

Hi,

At the beginning I'm sorry if this post is completely unrelated to
this mailing list.
I'm trying to find the base linux kernel version from which a patch
has been created and posted to LKML.
Most patches contain the index line. Is it the well known git index
(staging area) ?
Can I use the index to find the exact kernel version from which a
patch was created.
Please look at an example patch sent to LKML:
https://lkml.org/lkml/2015/5/14/497

It contains the following index line:
index 8dd1e55..9b0c81e 100644

I tried to find it using "git log" but I couldn't.

Please help me to determine the exact kernel version.

thanks in advance

If you call `git log --raw` (possibly adding --all) and then search for 8dd1e55, you should at least get to the revision when this file was changed to the revision that served as base for the patch. To make it faster, you could call `git log --raw -- <filename>`. That would also have the advantage that you could scroll up again to see which revision, if any, modified the file again, giving you kind of a commit range from which to pick.

Ciao,
