-oracleasm: Access d_bdev before dropping inode
-
-d_bdev is stored alongside the inode. If we hold the last reference to
-disk_inode, then iput() will clear the d_bdev field and cause a page
-fault when it is dereferenced. Further, the iput() could result in a
-blkdev_put(), after which our accesses to bdev could be further
-corrupted. To avoid all this, delay the iput() until all access to d,
-disk_inode, and bdev are complete.
