Subject: Re: [RFC] basic delayed allocation in VFS

It duplicates fs/mpage.c in bio building and introduces new generic API
(iomap, map_blocks_t, etc). In contrast, my trivial implementation re-use
existing code in fs/mpage.c, doesn't introduce new API and I tend to think
provides quite the same functionality. I can be wrong, of course ...

thanks, Alex
