Re: [PATCH] squashfs: Migrate from ll_rw_block usage to BIO

I don't see why you still need buffer_heads at all. Basically
if you replace each of your allocated buffer heads with a
simple page allocation the code will be much simpler (this version
adds more than 100 lines of code!) and probaby still a bit faster
as you don't need the squashfs_bio_request allocation either.
