The patch has been reviewed and approved by Christian König (maintainer). **Series Summary:** - **Scope**: Single patch fixing race condition in cross-process shared buffer handling - **Impact**: Fixes page faults when shared buffers are moved between processes/GPUs - **Risk**: Low - changes only synchronization behavior, not fundamental logic - **Stability candidate**: Yes - fixes a race condition that can cause GPU page faults **Key Concerns:** 1. The patch lacks a Cc: stable tag despite fixing a regression introduced by commit a448cb003edc 2. Christian König requested stable tag in review but this wasn't addressed 3. The fix is conceptually sound but testing coverage is unclear **Recommendation**: The patch should be merged with a Cc: stable@vger.kernel.org tag added. --- --- Generated by Claude Code Patch Reviewer
