From a7b75c5a8c41445f33efb663887ff5f5c3b4454b Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 23 Jul 2020 08:09:07 +0200 Subject: net: pass a sockptr_t into ->setsockopt Rework the remaining setsockopt code to pass a sockptr_t instead of a plain user pointer. This removes the last remaining set_fs(KERNEL_DS) outside of architecture specific code.
