If not let me know further instructions. Yes, thanks! So we see that reiserfs_security_init() returned bogus number 790797. This is caused by security_old_inode_init_security() either returning some bogus number or setting sec->length to something bogus. In any case it's some security module problem so I'm adding Mimi Zohar who did the changes in this code recently to CC. I'm also adding Rafael since this is a regression. Also I think he might use your kernel config so can you please send it? Thanks. Honza -- Jan Kara SUSE Labs, CR
