block_devcie is allocated from bdev_alloc() by bdev_alloc_inode(), and
currently block_device contains a pointer that point to the address of
inode, while such inode is allocated together:
bdev_alloc
inode = new_inode()
// inode is &bdev_inode->vfs_inode
bdev = I_BDEV(inode)
From: Yu Kuai
Changes in v2:
- split different portions into different patches, as greg k-h
suggested.
- use container_of() instead of "bdev + 1" to get the address of
bd_inode in the new helper, as grep k-h suggested.
Yu Kuai (16):
block: add a new helper to get inode from block_device
