Subject: bdi: fix use-after-free for dev_name(bdi->dev)
Date: Thu, 16 Apr 2020 09:15:11 +0200 [thread overview]
Message-ID: <20200416071519.807660-1-hch@lst.de> (raw)
Hi all,
the first three patches are my take on the proposal from Yufen Yu
to fix the use after free of the device name of the bdi device.
The rest is vaguely related cleanups.
