Increasing read request size in JFFS2

[payagond at aol.com]

Hi,
I want to know, whether, we can exploit the fast sequential read 
(multiple pages at one go) feature of a nand flash device by existing 
JFFS2 code.
read_pages in readahead decides to call either 
mapping->a_ops->readpages or mapping->a_ops->readpage
can I implement jffs2_readpages to do so?
The problem I feel is (if I have understood correctly)
To read more pages at one shot, we need to anyway read the 
jffs2_raw_inode header first and then calculate the lenth to read, will 
it give me more performance than what is existing?
regards
payagond
