dm fs?

What is the status of dmfs going into mainline?

I saw that Greg KH posted a patch with some corrections to dmfs for 2.5.50?

IMO it would be nice to have a kernel config option that makes the ioctl method optional when dmfs is set to y or m in kernel config. That will not only save a bit of code space, but it will also serve to encourage use of dmfs. :)

The last version I released is here:

http://people.sistina.com/~thornber/patches/2.5-unstable/2.5.51/2.5.51-dmfs-1.tar.bz2

There are still a couple of easy to fix issues with it (eg. the kmalloc while a spin lock is held that Andrew Morton pointed out :).

Both Andrew Morton and Greg KH expressed concerns with the way I've mapped the dm semantics onto the filesystem
(http://marc.theaimsgroup.com/?l=linux-kernel&m=103975736919315&w=2).
So Greg is currently trying to get a sysfs interface working.

We need to get a concensus of opinion in the community as to what is a good interface. I'm not going to be rushed into including something in dm that could cause critism for years to come. dmfs is what Alasdair Kergon and I have proposed, we're just waiting for an alternative to kick off the discussions ATM.

Yes, and hopefully I'll have something that works later this week, after I've dug out under this mount of email...

thanks,
