David Sterba db95c876c5 btrfs: submit superblock io with REQ_META and REQ_PRIO ... The superblock is also metadata of the filesystem so the relevant IO should be tagged as such. We also tag it as high priority, as it's the last block committed for metadata from a given transaction. Any delays would effectively block the whole transaction, also blocking any other operation holding the device_list_mutex.
