Re: [RFC][fat] use mpage_readpage when cluster size is page-alignment

hi,

I am not sure I am following you. Shouldn't do_mpage_readpage work for
all adjacent blocks regardless of whether block size is page-aligned
or not? What's is the performance problem you're thinking of?

                           Pekka

no, not block size but cluster size
as you know, in FAT, file is organized in clusters
and one cluster could have N blocks(sectors).
so if cluster size is not page-aligned,
a page may live in non-adjacent blocks, and
do_mpage_readpage has to fall back to block_read_full_page
in this case.

thanks.
                                  junjie
