Keith Busch 45b95d1615 block: Fix dev_t minor allocation lifetime ... commit 2da78092dd upstream. Releases the dev_t minor when all references are closed to prevent another device from acquiring the same major/minor. Since the partition's release may be invoked from call_rcu's soft-irq context, the ext_dev_idr's mutex had to be replaced with a spinlock so as not so sleep.
