Subject: [PATCH 4.4 09/30] xfs: Fix assert failure in xfs_setattr_size()
Date: Fri, 5 Mar 2021 13:22:38 +0100 [thread overview]
Message-ID: <20210305120849.856596955@linuxfoundation.org> (raw)
In-Reply-To: <20210305120849.381261651@linuxfoundation.org>
From: Yumei Huang <yuhuang@redhat.com>
commit 88a9e03beef22cc5fabea344f54b9a0dfe63de08 upstream.
An assert failure is triggered by syzkaller test due to
ATTR_KILL_PRIV is not cleared before xfs_setattr_size.
As ATTR_KILL_PRIV is not checked/used by xfs_setattr_size,
just remove it from the assert.
