Example #1

File: inode.c Project: AshishKumar4/seakernel

void fs_inode_init_kdev(struct inode *node)
{
	if(node->phys_dev && !node->kdev) {
		node->kdev = dm_device_get(MAJOR(node->phys_dev));
		if(node->kdev && node->kdev->create)
			node->kdev->create(node);
	}
}

Example #2

File: blockdev.c Project: Dennisbonke/DB-OS

void blockdev_register_partition(struct inode *master, struct inode *part, uint64_t partbegin, uint64_t partlen)
{
	struct blockdev *mbd = master->devdata;
	struct blockdev *pbd = kmalloc(sizeof(struct blockdev));
	pbd->ctl = mbd->ctl;
	pbd->partbegin = partbegin;
	pbd->partlen = partlen;
	part->devdata = pbd;
	part->phys_dev = master->phys_dev;
	part->kdev = dm_device_get(block_major);
}

Example #3
