> This PR introduces a `.git-blame-ignore-revs` file to the JDK repo root 
> directory. This file contains a list of git commit hashes that should be 
> excluded from consideration when running [git-blame 
> (1)](https://git-scm.com/docs/git-blame). This file is [automatically honored 
> by Github (with an escape 
> hatch)](https://docs.github.com/en/repositories/working-with-files/using-files/viewing-and-understanding-files#ignore-commits-in-the-blame-view).
>  Locally, however, every developer that wants to make use of this needs to 
> either configure it using [`git config 
> blame.ignoreRevsFile`](https://git-scm.com/docs/git-blame#Documentation/git-blame.txt-blameignoreRevsFile)
>  or specify it on the command line using [`git blame 
> --ignore-revs-file`](https://git-scm.com/docs/git-blame#Documentation/git-blame.txt---ignore-revs-filefile).
> 
> Initially, `.git-blame-ignore-revs` contains the commits associated with the 
> refactoring from `NULL` to `nullptr` in hotspot. Personally, it has already 
> happened to me multiple times that I ran `git blame` only to find one of 
> those commits. This could of course be solved with more complicated 
> `git`invocations. Maintaining this file of ignored revisions, however, gives 
> us a tool to alleviate this papercut from the already arduous process of 
> tracking down failures in the JDK.
