'struct dma_descriptor_metadata_ops' in not modified in these drivers. Constifying these structures moves some data to a read-only section, so increases overall security, especially when the structure holds some function pointers. On a x86_64, with allmodconfig, as an example: Before: ====== text data bss dec hex filename 120635 21584 64 142283 22bcb drivers/dma/xilinx/xilinx_dma.o After: ===== text data bss dec hex filename 120699 21520 64 142283 22bcb drivers/dma/xilinx/xilinx_dma.o Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Reviewed-by: Frank Li <Frank.Li@nxp.com> Reviewed-by: Sai Sree Kartheek Adivi <s-adivi@ti.com> Reviewed-by: Manivannan Sadhasivam <mani@kernel.org> Reviewed-by: Radhey Shyam Pandey <radhey.shyam.pandey@amd.com> Link: https://patch.msgid.link/b0a22171f3ed68e156a2fa84383e99c23ec6b2ff.1784037977.git.christophe.jaillet@wanadoo.fr Signed-off-by: Vinod Koul <vkoul@kernel.org> |
