From b0ea0fa5435f9df7213a9af098558f7dd584d8e8 Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Wed, 9 Jan 2019 11:15:16 +0200 Subject: IB/{core,hw}: Have ib_umem_get extract the ib_ucontext from ib_udata ib_umem_get() can only be called in a method callback, which always has a udata parameter. This allows ib_umem_get() to derive the ucontext pointer directly from the udata without requiring the drivers to find it in some way or another.
