Christoph Hellwig d6c434ae9d bdi: add a ->dev_name field to struct backing_dev_info 
[ Upstream commit 6bd87eec23 ]

Cache a copy of the name for the life time of the backing_dev_info
structure so that we can reference it even after unregistering.

Fixes: 68f23b8906 ("memcg: fix a crash in wb_workfn when a device disappears")
