Look at this quick, dirty hack:

        printk("rd->nsize before memcpy: %x\n", rd->nsize);
        printk("rd->name: %c %x\n", rd->name[0], rd->name[0]);
        printk("rd->name: %c %x\n", rd->name[11], rd->name[11]);
        printk("rd->name: %c %x\n", rd->name[12], rd->name[12]);
        printk("rd->name: %c %x\n", rd->name[13], rd->name[13]);
        memcpy(&fd->name, rd->name, rd->nsize);
        printk("rd->nsize after memcpy: %x\n", rd->nsize);
        printk("rd->name: %c %x\n", rd->name[0], rd->name[0]);
        printk("rd->name: %c %x\n", rd->name[11], rd->name[11]);
        printk("rd->name: %c %x\n", rd->name[12], rd->name[12]);
        printk("rd->name: %c %x\n", rd->name[13], rd->name[13]);


rd->nsize before memcpy: 14

        printk("rd->nsize before memcpy: %x\n", rd->nsize);
        printk("rd->name: %c %x\n", rd->name[0], rd->name[0]);
        printk("rd->name: %c %x\n", rd->name[14], rd->name[14]);
        printk("rd->name: %c %x\n", rd->name[15], rd->name[15]);
        printk("rd->name: %c %x\n", rd->name[16], rd->name[16]);
        printk("rd->name: %c %x\n", rd->name[17], rd->name[17]);
        memcpy(&fd->name, rd->name, rd->nsize);
        printk("rd->nsize after memcpy: %x\n", rd->nsize);
        printk("rd->name: %c %x\n", rd->name[0], rd->name[0]);
        printk("rd->name: %c %x\n", rd->name[14], rd->name[14]);
        printk("rd->name: %c %x\n", rd->name[15], rd->name[15]);
        printk("rd->name: %c %x\n", rd->name[16], rd->name[16]);
        printk("rd->name: %c %x\n", rd->name[17], rd->name[17]);



rd->nsize before memcpy: 16
rd->name: o 6f             
rd->name: e 65
rd->name: y 79
rd->name: g 67
rd->name: e 65
rd->nsize after memcpy: 16
rd->name: o 6f            
rd->name: e 65
rd->name: y 79
rd->name: g 67
rd->name: e 65
fd->name: openssh-host-key
jffs2_scan_dirent_node(): Name CRC failed on node at 0x003a52c8: Read 0x839452cb, calculated 0x262752af
Name for which CRC failed is (now) 'openssh-host-key', ino #350

So rd->name and rd->size seems to be both ok just before and after memcpy.

Weird...
