Subject: [PATCH 03/28] ext4: lock inode before calling ext4_orphan_add()
Date: Wed, 31 May 2017 01:14:52 -0700 [thread overview]
Message-ID: <20170531081517.11438-3-tahsin@google.com> (raw)
In-Reply-To: <20170531081517.11438-1-tahsin@google.com>
ext4_orphan_add() requires caller to be holding the inode lock.
Add missing lock statements.
