Jeff Mahoney cea67ab92d btrfs: clean the old superblocks before freeing the device ... btrfs_rm_device frees the block device but then re-opens it using the saved device name. A race exists between the close and the re-open that allows the block size to be changed. The result is getting stuck forever in the reclaim loop in __getblk_slow. This patch moves the superblock cleanup before closing the block device, which is also consistent with other callers. We also don't need a private copy of dev_name as the whole routine operates under the uuid_mutex.
