From 931ca7ab7fe804d77bc6952f1512950c0d870f26 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sun, 29 Mar 2020 17:18:30 -0400 Subject: ip*_mc_gsfget(): lift copyout of struct group_filter into callers pass the userland pointer to the array in its tail, so that part gets copied out by our functions; copyout of everything else is done in the callers. Rationale: reuse for compat; the array is the same in native and compat, the layout of parts before it is different for compat.
