Hi,
 
I know sequence number is the block allocation order, but i am wonder does the order of sequence number is also the creation time order of files?  I know when yaffs perform gc, if that block contains useful object header it will copies it to a new block whcih has the currently largest sequence number, but the time for that header maybe very old.  Is that correct? Moreover, how does yaffs deal with cold and hot data? Thank you.
