From 9f961b57568960a150cc9781c52824c9093a0514 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Sun, 16 Dec 2007 16:59:31 +0200 Subject: UBI: add UBI control device This patch is a preparation to make UBI devices dynamic. It adds an UBI control device which has dynamically allocated major number and registers itself as "ubi_ctrl". It does not do anything so far. The idea is that this device will allow to attach/detach MTD devices from userspace. This is symilar to what the Linux device mapper has. The next things to do are: * Fix UBI, because it now assumes UBI devices cannot go away * Implement control device ioctls which will attach/detach MTD devices Signed-off-by: Artem Bityutskiy --- drivers/mtd/ubi/ubi.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'drivers/mtd/ubi/ubi.h') diff --git a/drivers/mtd/ubi/ubi.h b/drivers/mtd/ubi/ubi.h index 994233d6e1e3..21c028366fd2 100644 --- a/drivers/mtd/ubi/ubi.h +++ b/drivers/mtd/ubi/ubi.h @@ -235,7 +235,7 @@ struct ubi_wl_entry; /** * struct ubi_device - UBI device description structure - * @dev: class device object to use the the Linux device model + * @dev: UBI device object to use the the Linux device model * @cdev: character device object to create character device * @ubi_num: UBI device number * @ubi_name: UBI device name @@ -398,6 +398,7 @@ struct ubi_device { extern struct kmem_cache *ubi_ltree_slab; extern struct kmem_cache *ubi_wl_entry_slab; +extern struct file_operations ubi_ctrl_cdev_operations; extern struct file_operations ubi_cdev_operations; extern struct file_operations ubi_vol_cdev_operations; extern struct ubi_device *ubi_devices[]; -- cgit v1.2.1
