From 7601d81506ef23dea9ea44015dcc45c911797a85 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Wed, 1 May 2019 11:05:41 -0700 Subject: [PATCH] gcc-9: silence 'address-of-packed-member' warning commit 6f303d60534c46aa1a239f29c321f95c83dda748 upstream. We already did this for clang, but now gcc has that warning too. Yes, yes, the address may be unaligned. And that's kind of the point.
