mtd/ubi/gluebi.c

9  * This is a small driver which implements fake MTD devices on top of UBI
12  * UBI.
15  * size (@mtd->writesize) is equivalent to the UBI minimal I/O unit. The
26 #include <linux/mtd/ubi.h>
28 #include "ubi-media.h"
38  * @desc: UBI volume descriptor
39  * @ubi_num: UBI device number this gluebi device works on
40  * @vol_id: ID of UBI volume this gluebi device works on
58  * @ubi_num: UBI device number
61  * This function seraches for gluebi device corresponding to UBI device
62  * @ubi_num and UBI volume @vol_id. Returns the gluebi device description
99 		 * readers/writers/exclusive/meta openers as UBI does. So we do  in gluebi_get_device()
100 		 * not open the UBI volume again - just increase the reference  in gluebi_get_device()
109 	 * This is the first reference to this UBI volume via the MTD device  in gluebi_get_device()
270  * gluebi_create - create a gluebi device for an UBI volume.
271  * @di: UBI device description object
272  * @vi: UBI volume description object
274  * This function is called when a new UBI volume is created in order to create
323 		err_msg("gluebi MTD device %d form UBI device %d volume %d already exists",  in gluebi_create()
342  * @vi: UBI volume description object
344  * This function is called when an UBI volume is removed and it removes
357 		err_msg("got remove notification for unknown UBI device %d volume %d",  in gluebi_remove()
371 		err_msg("cannot remove fake MTD device %d, UBI device %d, volume %d, error %d",  in gluebi_remove()
385  * gluebi_updated - UBI volume was updated notifier.
388  * This function is called every time an UBI volume is updated. It does nothing
402 		err_msg("got update notification for unknown UBI device %d volume %d",  in gluebi_updated()
414  * gluebi_resized - UBI volume was re-sized notifier.
417  * This function is called every time an UBI volume is re-size. It changes the
429 		err_msg("got update notification for unknown UBI device %d volume %d",  in gluebi_resized()
439  * gluebi_notify - UBI notification handler.
