Subject: Re: [RFC] basic delayed allocation in VFS
Date: Thu, 26 Jul 2007 17:33:08 +0400	[thread overview]
Message-ID: <46A8A294.2070106@clusterfs.com> (raw)
In-Reply-To: <46A88DFD.7030609@garzik.org>

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
