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

[Vitaly Wool]

Hi Charles,

no it's not yet in CVS. I think I'll be able to commit it if we get any 
positive feedback on this patch (i. e. if it's actually working for 
anyone else than me :))
As for write_oobfree, it looks to be  useful for JFFSx to stop messing 
with oobinfos in JFFSx code.

Best regards,
   Vitaly
