Hi, This is the 6th version of the patch. The only change compared with 5th version is: I replace jffs2_cleanmarker_oob() with jffs2_ebh_oob() to avoid confusion since cleanmarker is gone. The patch is at: http://www.infradead.org/~forrest/eraseblock_header_r6.patch Your comments are welcome. Thanks, Forrest
