Padding node

[Artem B. Bityuckiy]

Hello.

Could anybody please explain why "padding nodes" are uses (I mean 
JFFS2_NODETYPE_PADDING node type).

JFFS2 uses these nodes only in case of NAND flash in order to fill the 
end if Flash pages. In case of small ending space, JFFS2 uses 
JFFS2_DIRTY_BITMASK padding. Why don't it always use JFFS2_DIRTY_BITMASK?

Is this just to speed-up the future mount time because padding node is 
scanned faster then continuous filling?

Why the same padding nodes aren't used in case of NOR flashes?

Thanks.
