Code Review
This pull request is a large-scale refactoring to remove circular dependencies by deleting the vllm/attention/__init__.py file and updating all import paths to use full, direct paths. This is a sound software engineering practice that improves the codebase's structure and maintainability. I have reviewed all the changes across the numerous files, and they appear to be correct and consistent with the stated goal. The modifications are mostly mechanical, replacing old import paths with new, more specific ones. Given the nature of these changes and the fact that they are a correct refactoring, I have not found any issues of high or critical severity to report.

LGTM, this interface is internal and clear enough to update the import if it fails in external code

Purpose
The
vllm/attentionmodule is coupled to the rest of the codebase, so the imports invllm/attention/__init__.pyfrequently cause circular imports, leading to the use ofTYPE_CHECKING.This issue is an obstacle to #26315 , which cannot use
TYPE_CHECKINGimports becauseAttentionConfigis a dataclass.This PR empties
__init__.pyand updates the rest of the codebase to use full-path imports.Test Plan
CI should suffice. Recommend to run all tests.
