From: Jason Gunthorpe Date: Thu, 30 Jul 2015 23:22:22 +0000 (-0600) Subject: IB/srp: Use pd->local_dma_lkey X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e6bf5f48d2adc443689c5e627bcd559b00201e5c;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git IB/srp: Use pd->local_dma_lkey Replace all leys with pd->local_dma_lkey. This driver does not support iWarp, so this is safe. The insecure use of ib_get_dma_mr is thus isolated to an rkey, and will have to be fixed separately.
