43  * UBI volume creation
50  * UBI volume deletion
53  * To delete a volume, the %UBI_IOCRMVOL ioctl command of the UBI character
54  * device should be used. A pointer to the 32-bit volume ID hast to be passed
57  * UBI volume re-size
60  * To re-size a volume, the %UBI_IOCRSVOL ioctl command of the UBI character
71  * UBI volume update
74  * Volume update should be done via the %UBI_IOCVOLUP ioctl command of the
75  * corresponding UBI volume character device. A pointer to a 64-bit update
77  * this number of bytes to the volume character device. The update is finished
78  * when the claimed number of bytes is passed. So, the volume update sequence
90  * corresponding UBI volume character device should be used. This command
98  * ioctl command of the corresponding UBI volume character device. A pointer to
101  * should be done in case of the "volume update" ioctl).
131  * Set an UBI volume property
134  * To set an UBI volume property the %UBI_IOCSETPROP ioctl command should be
142  * To create a R/O block device on top of an UBI volume the %UBI_IOCVOLCRBLK
151  * When a new UBI volume or UBI device is created, users may either specify the
152  * volume/device number they want to create or to let UBI automatically assign
158 /* Maximum volume name length */

222  * UBI volume type constants.
224  * @UBI_DYNAMIC_VOLUME: dynamic volume

302  * UBI volume flags.
304  * @UBI_VOL_SKIP_CRC_CHECK_FLG: skip the CRC check done on a static volume at
306  *				should only be used if the volume user has a
316  * struct ubi_mkvol_req - volume description data structure used in
317  *                        volume creation requests.
318  * @vol_id: volume number
319  * @alignment: volume alignment
320  * @bytes: volume size in bytes
321  * @vol_type: volume type (%UBI_DYNAMIC_VOLUME or %UBI_STATIC_VOLUME)
322  * @flags: volume flags (%UBI_VOL_SKIP_CRC_CHECK_FLG)
323  * @name_len: volume name length
325  * @name: volume name
330  * The @alignment field specifies the required alignment of the volume logical
335  * To put it differently, the logical eraseblock of this volume may be slightly
341  * a block device on top of an UBI volume. In this case, it is desirable to fit
342  * an integer number of blocks in logical eraseblocks of this UBI volume. With
343  * alignment it is possible to update this volume using plane UBI volume image
358  * struct ubi_rsvol_req - a data structure used in volume re-size requests.
359  * @vol_id: ID of the volume to re-size
360  * @bytes: new size of the volume in bytes
365  * volume, it must be wiped out first (by means of volume update operation with
377  * @vol_id: ID of the volume to re-name
380  * @name: new volume name
386  * The UBI volume re-name operation is atomic, which means that should power cut
400  * In other words, in case of re-naming into an existing volume name, the
401  * existing volume is removed, unless it is re-named as well at the same
453  * struct ubi_set_vol_prop_req - a data structure used to set an UBI volume
