Subject: block device without page cache buffering
Date: Thu, 30 Dec 2010 15:37:31 +0100 [thread overview]
Message-ID: <20101230143731.GO9658@belle.intranet.vanheusden.com> (raw)
Hi,
What should a block device driver need to do to get all read/write
requests without any buffering from the page cache?
I think the iscsi initiation does this.
This is needed to get an existing pseudo block device to function as a
shared storage so that a cluster filesystem (gpfs/ocfs) can be put on it (nbd).
