Then\nI splat the patch to ease review and ensure most can ship without\nrevert. It has been split in 12 patches.\n\nOriginal change\u0027s description:\n-----------------------------\nConvert to UNSAFE_TODO in partition_alloc\n\nThis is an automated #cleanup patch using the [Script] below.\n\nWe are migrating from coarse-grained file-level suppression (#pragma\nallow_unsafe_buffers) to granular, expression-level markers\n(UNSAFE_TODO()). The pragma disables safety checks for an entire file,\nwhereas UNSAFE_TODO() isolates specific potentially unsafe operations,\nallowing the rest of the file to be enforced as safe.\n\nThis CL was uploaded by git cl split.\n\nScript: https://docs.google.com/document/d/1ORQGBNn2R-CEvNbDTjRd-GrOBOFlCxIHdcvSUA_EhR4/edit?usp\u003dsharing\nAX-Relnotes: N/A\nCleanup: This is an automated #cleanup.\nBug: 409340989\nChange-Id: If17e71223f4e985dfa8f25ee6e8f4ac4a08cc91e\nReviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/7197825\nReviewed-by: Keishi Hattori \u003ckeishi@chromium.org\u003e\nAuto-Submit: Arthur Sonzogni \u003carthursonzogni@chromium.org\u003e\nCommit-Queue: Keishi Hattori \u003ckeishi@chromium.org\u003e\nCr-Commit-Position: refs/heads/main@{#1551922}\nNOKEYCHECK\u003dTrue\nGitOrigin-RevId: 9e0011188b2b486e63b99dfc73db42ba71c68203\n" }, { "commit": "af595168d6ebc1aa751159affaf0d7f8c1b6e520", "tree": "0378c8b7d23950b5a2f8c5c6a3157222e4b1e7d5", "parents": [ "ee9dae5f4046d8f40a2559250b6067691f10683c" ], "author": { "name": "Lei Zhang", "email": "thestig@chromium.org", "time": "Fri Nov 28 09:25:03 2025" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Fri Nov 28 09:29:54 2025" }, "message": "Forward declare PartitionRoot in scheduler_loop_quarantine_support.h\n\nAvoid including partition_root.h in 5000+ TUs.\n\nChange-Id: I3a5a7d4ae3a095ea72a6440dc8e99b6d8b38ce61\nReviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/7209139\nCommit-Queue: Mikihito Matsuura \u003cmikt@google.com\u003e\nCommit-Queue: Lei Zhang \u003cthestig@chromium.org\u003e\nAuto-Submit: Lei Zhang \u003cthestig@chromium.org\u003e\nReviewed-by: Mikihito Matsuura \u003cmikt@google.com\u003e\nCr-Commit-Position: refs/heads/main@{#1551376}\nNOKEYCHECK\u003dTrue\nGitOrigin-RevId: 62d1f9c0c0dde7b6dc04c6c6af8c005ba6c28ef3\n" } ], "next": "ee9dae5f4046d8f40a2559250b6067691f10683c" }
