* drivers: Introduce dev_set_name()Andrey Smirnov2018-10-181-2/+2
| | | | | | | | Introduce dev_set_name() in order to hide implementation details of setting device's name so it'd be easier to change it. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* UBI: hide EBA internalsBoris Brezillon2018-08-311-22/+16
| | | | | | | | | | | | | | | Create a private ubi_eba_table struct to hide EBA internals and provide helpers to allocate, destroy, copy and assing an EBA table to a volume. Now that external EBA users are using helpers to query/modify the EBA state we can safely change the internal representation, which will be needed to support the LEB consolidation concept.

* ubi: Make volume resize power cut awareRichard Weinberger2018-08-311-7/+18
| | | | | | | | | | | | | | | | | | | When the volume resize operation shrinks a volume, LEBs will be unmapped. Since unmapping will not erase these LEBs immediately we have to wait for that operation to finish. Otherwise in case of a power cut right after writing the new volume table the UBI attach process can find more LEBs than the volume table knows. This will render the UBI image unattachable. Fix this issue by waiting for erase to complete and write the new volume table afterward.

* UBI: Clean up return in ubi_remove_volume()Dan Carpenter2018-08-311-1/+1
| | | | | | | | | | | My static checker says that "err" can be uninitialized if "vol->reserved_pebs" is <= 0. I don't think that can happen but returning a literal is cleaner anyway.

* UBI: Extend UBI layer debug/messaging capabilitiesTanya Brokhman2016-05-271-32/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If there is more then one UBI device mounted, there is no way to distinguish between messages from different UBI devices. Add device number to all ubi layer message types. The R/O block driver messages were replaced by pr_* since ubi_device structure is not used by it. Amended a bit by Artem.
