Subject: [PATCH net-next] drivers:net: dma_alloc_coherent: use __GFP_ZERO
instead of memset(, 0)
Reduce the number of calls required to alloc a zeroed block of memory.
Trivially reduces overall object size.
Other changes around these removals
o Neaten call argument alignment
o Remove an unnecessary OOM message after dma_alloc_coherent failure o Remove
unnecessary gfp_t stack variable

Hi Joe,
Your changes did not seem to make it to igbvf/netdev.c - I think instead of
removing an extra line added for code clarity, you want to add:
"tx_ring->desc = dma_alloc_coherent(&pdev->dev, tx_ring->size,
&tx_ring->dma, GFP_KERNEL|
__GFP_ZERO);"
Regards,
Akeem Abodunrin
