The branch main has been updated by alc: URL: https://cgit.FreeBSD.org/src/commit/?id=32e82bcc152783dfe0d03ffdd864cedfddbc80d7 commit 32e82bcc152783dfe0d03ffdd864cedfddbc80d7 Author: Alan Cox <alc@FreeBSD.org> AuthorDate: 2022-06-20 18:40:42 +0000 Commit: Alan Cox <alc@FreeBSD.org> CommitDate: 2022-06-21 04:03:04 +0000 busdma_iommu: Eliminate a redundant trunc_page() Since OFF_TO_IDX() inherently truncates the given value, there is no need to perform trunc_page() on it.
