From: Xiang Gao Date: Wed, 15 Apr 2026 05:41:01 +0000 (+0800) Subject: dma-buf: fix stale @lock references in struct dma_buf documentation X-Git-Tag: v7.1-rc2~7^2~2^2~9 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0b13173d27fa15679463b62a10cfa8b3d6c3a71c;p=thirdparty%2Fkernel%2Flinux.git dma-buf: fix stale @lock references in struct dma_buf documentation The kernel-doc comments for vmapping_counter and vmap_ptr in struct dma_buf reference "@lock" as the protecting lock, but struct dma_buf no longer has a "lock" member. The mutex was removed in favor of using the dma_resv lock exclusively. The implementation correctly uses dma_resv_assert_held(dmabuf->resv) in dma_buf_vmap() and dma_buf_vunmap(), so update the documentation to reference @resv instead.
