Subject: Claude review: rust: dma: add zeroed constructor to `Coherent`
Date: Sun, 22 Mar 2026 03:23:43 +1000 [thread overview]
Message-ID: <review-patch3-20260320194626.36263-4-dakr@kernel.org> (raw)
In-Reply-To: <20260320194626.36263-4-dakr@kernel.org>
Patch Review
Adds `zeroed`, `zeroed_with_attrs`, `zeroed_slice`, and `zeroed_slice_with_attrs`. All delegate to the private `alloc_with_attrs` / `alloc_slice_with_attrs` with `__GFP_ZERO` ORed into the flags.
**Double zeroing concern**: If a caller passes `GFP_KERNEL | __GFP_ZERO` to `zeroed()`, the flag will be ORed again (no-op but semantically redundant). The naming makes this clear enough — callers of `zeroed` shouldn't also pass `__GFP_ZERO`.
The sample driver update (`rust_dma.rs`) correctly converts from the old `alloc_coherent` to `zeroed_slice`. Clean.
