I want to remove this allocation, but I don't know if this is possible, what are the disadvantages....? (my basic problem is that I have not enough RAM on my board, but it is too late to change HW for the running projects) After reading some jffs2 documentation, I think that my problem is the inode cache? Kind regards, Juergen Lambrecht
