ubifs error : read_znode: bad indexing node

[Matthieu CASTET]

Hi,

we have products where rw ubifs partition are corrupted.
They all failed with the "read_znode: bad indexing node at LEB 558:22056, error
6" or "read_znode: bad indexing node at LEB 446:62888, error 2".

The last ubifs stable commit we have is
http://git.infradead.org/users/dedekind/ubifs-v2.6.32.git/commit/7eb3b6c0999bd2cbc37adb2bd0fb8127f98240ea
.


Do you know if the bug is known ?
Google doesn't provide any info on this and looking at ubifs new commits don't
provide explicit bug fix.

Are there any document that explain how znode works ?
