From 0a384abfae66651b28e4bbe16883b1ff046ba3b3 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 27 Feb 2020 08:11:20 -0700 Subject: net: abstract out normal and compat msghdr import This splits it into two parts, one that imports the message, and one that imports the iovec. This allows a caller to only do the first part, and import the iovec manually afterwards. No functional changes in this patch.
