Dma_pool_zalloc combines dma_pool_alloc and memset 0. The semantic patch that makes this transformation is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ type T; T *d; expression e; statement S; @@ d = - dma_pool_alloc + dma_pool_zalloc (...); if (!d) S - memset(d, 0, sizeof(T)); @@ expression d,e; statement S; @@ d = - dma_pool_alloc + dma_pool_zalloc (...); if (!d) S - memset(d, 0, sizeof(*d)); // </smpl> --- drivers/crypto/marvell/tdma.c | 5 ++--- drivers/dma/fsldma.c | 3 +-- drivers/dma/ioat/init.c | 5 ++--- drivers/dma/mmp_pdma.c | 3 +-- drivers/dma/xilinx/xilinx_vdma.c | 3 +-- 5 files changed, 7 insertions(+), 12 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
