[PATCH] treat OOB as a single chunk of oobavail bytes

[Vitaly Wool]

Hi Yuri,

well, lemme just summarize what you hafta do in order to make YAFFS2 
work with my patches.

1. Apply the following patch to the mtd code:
http://lists.infradead.org/pipermail/linux-mtd/2005-December/014648.html
(yes, it's a single patch!)
2. Modify the fs/yaffs2/yaffs_mtdif2.c to use read_oobfree/write_oobfree 
where appropriate.

Hope that helps,

   Vitaly
