Doesn't this case many re-erases at each mount time?

BTW: I tried your patch in nandsim, jffs2 was unhappy.
[   56.147361] jffs2: notice: (440) jffs2_build_xattr_subsystem: complete building xattr subsystem, 0 of xdatum (0 unchecked, 0 orphan) and 0 of xref (0 dead, 0 orphan) found.
[   56.200438] nand: nand_do_write_ops: attempt to write non page aligned data
[   56.201090] jffs2: Write clean marker to block at 0x001f8000 failed: -22

Do you have an idea?

Thanks,
