It refers to "changelist". Google uses a Perforce-like VCS internally, and they kept the Perforce terminology: https://www.perforce.com/perforce/doc.051/manuals/p4guide/07...

aka "Pull Request" in Github parlance.

[hota_mazi]

aka "Merge Request" in Gitlab vernacular (which makes more sense than "pull request" in my opinion).

[aledalgrande]

aka "patch" for the Linux kernel development community

[xixixao]

aka "diff" or "revision" at FB .)

Yeah, merge request seems like the best terminology of the ones I've seen.

A Perforce changelist is more like a git commit than a GitHub pull request.

The way Google uses it, a "CL" means both "a thing you sent out for pre-commit review" and "a submitted change". It's very similar to a GitHub PR, if you use a master branch and always squash your PRs when merging to master.
