Subject: OO swap interface
Date: Thu, 11 Oct 2001 06:30:47 -0500	[thread overview]
Message-ID: <3BC582E7.C2C4FCC7@davidnicol.com> (raw)
In-Reply-To: <1355693A51C0D211B55A00105ACCFE6402B9E013@ATL_MS1> <20011010095536.C10443@turbolinux.com>


Here's an idea that has been mulling under my mullet for 
the last few weeks:

the nbd can be used for a swap device, but since swap has no reason
to inform the drive about what parts of it are free, it is not possible
to have a central nbd server overcommit for multiple client swapping
nodes.

Therefore I wonder how tricky it would be to create a swap interface
that is ignorant of disk geometries.   the swap interface language
would accept requests for space, with unique handles, and would
return the swapped-out data on representation of the handle.  Like
a virtual memory hat check.
