Sorry, we're seriously, seriously, seriously short on flags in the page struct and this patch is going to need one heck of a good case for it to be acceptable.
Even then, we should put a lot of effort into finding some way of avoiding adding that page flag. One option might be to add a new radix-tree tag, and defining it as "for filesytem usage". Or use PG_checked (which should be renamed to to PG_fs_misc) (if that doesn't conflict with ext4's existing use of PG_checked). Or use !PageMappedToDisk()? These patches seem to have a number of issues - we should get them properly commented and properly changelogged then get them on the wire for decent review before investing too much in them, please. - To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
