  Linux Kernel Shallow Bundles







 













## Why we need this?

- Full, non-shallow clones of Linux kernel trees are multiple gigabytes in size, and take a lot of time to process.

- Shallow clones are much smaller, but cloning/fetching shallow trees impose a huge load on the git server

- `kernel.org` has [git bundles](https://git-scm.com/docs/git-bundle) available for download over HTTPS/CDN (simple file download) and [recommend their use](https://www.kernel.org/best-way-to-do-linux-clones-for-your-ci.html) - [instructions](https://www.kernel.org/cloning-linux-from-a-bundle.html) 

- This repository does the heavy lifting. Grabbing bundles, updating them from live git servers, makes them shallow and ready for consumption.

  - Produced shallow bundles are around 250 Mb as of 5.18.y

  - Produced shallow bundles include all tags for the version involved, including `-rc` tags

  - Scheduled runs update bundles daily, using GitHub actions, including caching.
