[Xen-devel] [PATCH 06 of 10] blkfront: Fix blkfront backend switch race (bdev open)

[Daniel Stodden <daniel.stodden@xxxxxxxxxx>]

We need not mind if users grab a late handle on a closing disk. We
probably even should not. But we have to make sure it's not a dead
one already

Let the bdev deal with a gendisk deleted under its feet. Takes the
info mutex to decide a race against backend closing.
