Understanding jffs2 warning message

[Jean-Philippe Francois <jp.francois@cynove.com>]

Hi,

I am doing some test on a JFFS2 file system.
It is installed on a Macronix Flash 29LV320, with top boot block.
The part are cfi probed, and it works (almost) fine.

I am doing some tar/untar loop [1]. Every six or seven loop, I have a
serie of 8 warning messages :

Node totlen on flash (0xffffffff) != totlen in node ref (0x00001040)
Node totlen on flash (0xffffffff) != totlen in node ref (0x00001044)
Node totlen on flash (0xffffffff) != totlen in node ref (0x00001044)
Node totlen on flash (0xffffffff) != totlen in node ref (0x00001044)
Node totlen on flash (0xffffffff) != totlen in node ref (0x00001044)
Node totlen on flash (0xffffffff) != totlen in node ref (0x00001044)
Node totlen on flash (0xffffffff) != totlen in node ref (0x00001044)
Node totlen on flash (0xffffffff) != totlen in node ref (0x00000768)

I looked at the code, but I don't understand what is the meaning of
these messages.
Do you think it can be related to the Top Boot Block layout of this
flash (ie last 64 k sector is replaced by 8 8k sector) ?
I might be wrong, but I think the sector layout and erase size is taken
into account by CFI probing ?
