From: Mark Bloch Date: Thu, 27 Oct 2016 13:36:30 +0000 (+0300) Subject: IB/core: Save QP in ib_flow structure X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8ecc7985b4b15f1f14bce31d8ab45dc426df7da3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git IB/core: Save QP in ib_flow structure When we create flow steering rule, we need to save the related QP in the ib_flow struct. this QP is used in destroy flow. Move the QP assignment from ib_uverbs_ex_create_flow into ib_create_flow, this would allow both kernel and userspace consumers to use it. This bug wasn't seen in the wild because there are no kernel consumers currently in the kernel.
