fs/block_dev.c: __read_mostly improvement and sb_is_blkdev_sb utilization
- iget5_locked in bdget really needs blockdev_superblock, instead of bd_mnt, so bd_mnt could be just a local variable; - blockdev_superblock really needs __read_mostly, while local var bd_mnt not; - make use of sb_is_blkdev_sb in bd_forget, instead of direct reference to blockdev_superblock.
