+Subject: lockd: lost rollback of set_grace_period() in lockd_down_net()
+
+From: Vasily Averin <vvs@virtuozzo.com>
+
+commit 3a2b19d1ee5633f76ae8a88da7bc039a5d1732aa upstream.
+
+Commit efda760fe95ea ("lockd: fix lockd shutdown race") is incorrect,
+it removes lockd_manager and disarm grace_period_end for init_net only.
+
+If nfsd was started from another net namespace lockd_up_net() calls
+set_grace_period() that adds lockd_manager into per-netns list
+and queues grace_period_end delayed work.
+
+These action should be reverted in lockd_down_net().
+Otherwise it can lead to double list_add on after restart nfsd in netns,
+and to use-after-free if non-disarmed delayed work will be executed after netns destroy.

+Subject: Revert "ARM: dts: imx6qdl-wandboard: Fix audio channel swap"
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+This reverts commit 9de3a3bfed892608dc30a6bc3fd8bdbeae5b51a5 which was
+commit 79935915300c5eb88a0e94fa9148a7505c14a02a upstream.
+
+As Ben points out:
+       This depends on:
+
+       commit 570c70a60f53ca737ead4e5966c446bf0d39fac9
+       Author: Fabio Estevam <fabio.estevam@nxp.com>
+       Date:   Wed Apr 5 11:32:34 2017 -0300
+
+           ASoC: sgtl5000: Allow LRCLK pad drive strength to be changed
+
+which did not show up until 4.13, so this makes no sense to have in this
+stable branch.
