SuSe 9.3 kernel 2.6.11.4-21.11-smp warning: vs-8115: get_num_ver: not directory or indirect item error

SuSe 9.3 kernel 2.6.11.4-21.11-smp warning: vs-8115: get_num_ver: not directory or indirect item error

[Brad Dameron]

I am seeing a lot of these errors:

ReiserFS: sda7: warning: vs-8115: get_num_ver: not directory or indirect
item

I did a google search and all I see is emails back from 2004/2005 about
it being a issue with the 2.6.8 kernel. Are these warnings something I
should run reiserfsck on the partition to correct or something I should
ignore? This is on a production server and I would hate to lose the
data.

Thanks,

it is just interesting case. I think that this warning can be removed if
everything works normally.

But, would you, please, apply the attached patch and reproduce this
warning and send me kernel output so that I can see the case which was
considered impossible.
