From e64a0e16928415648d53d721b3d6fc3635eddf92 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 14 Apr 2020 09:42:21 +0200 Subject: block: remove RQF_COPY_USER The RQF_COPY_USER is set for bio where the passthrough request mapping helpers decided that bounce buffering is required. It is then used to pad scatterlist for drivers that required it. But given that non-passthrough requests are per definition aligned, and directly mapped pass-through request must be aligned it is not actually required at all.
