[PATCH v3 11/24] RDMA/nes: Remove call to memset after pci_alloc_consistent

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



pci_alloc_consitent calls dma_alloc_coherent directly.
In commit 518a2f1925c3
("dma-mapping: zero memory returned from dma_alloc_*"),
dma_alloc_coherent has already zeroed the memory.
So memset is not needed.
