UBI: Fastmap: Care about the protection queue

2015-01-28T15:09:45Z

Fastmap can miss a PEB if it is in the protection queue and not jet in the used tree. Treat every protected PEB as used. Signed-off-by: Richard Weinberger Signed-off-by: Artem Bityutskiy

UBI: Extend UBI layer debug/messaging capabilities

2014-11-07T10:08:51Z

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. Signed-off-by: Tanya Brokhman Signed-off-by: Artem Bityutskiy

UBI: fastmap: do not miss bit-flips

2014-07-16T05:32:00Z

The return value from 'ubi_io_read_ec_hdr()' was stored in 'err', not in 'ret'. This fix makes sure Fastmap-enabled UBI does not miss bit-flip while reading EC headers, events and scrubs the affected PEBs. This issue was reported by Coverity Scan.

UBI: fix the volumes tree sorting criteria

2014-07-01T06:23:03Z

Commig "604b592 UBI: fix rb_tree node comparison in add_map" broke fastmap backward compatibility and older fastmap images cannot be mounted anymore. The reason is that it changes the volumes RB-tree sorting criteria. This patch fixes the problem.

The comparisons used in add_vol() shouldn't be identical. Pretty sure the following is correct but it is completely untested. Signed-off-by: Mike Snitzer Acked-by: Richard Weinberger Signed-off-by: Artem Bityutskiy
