Team device driver [3.3]
+
+ -
+ Alternative to the bonding driver - simpler, modular, high-level
+ control deferred to userland
+
+ -
+ Basic configuration can be done with ip, but it really
+ needs new tools - teamd, teamnl, etc.
+
+ -
+ Make it work: see
+ http://bugs.debian.org/695850

Transcendent memory [3.0-3.5]
+
+ -
+ Abstract storage for memory pages, expected to be slower than
+ regular memory but faster than disk
+
+ -
+ Can provide a second layer of page cache (cleancache and frontswap)
+
+ -
+ Pages stored by hypervisor (Xen), compressed local memory
+ (zcache) or cluster of machines (RAMster)
+
+ -
+ Not yet enabled in Debian kernels, and needs some thought about
+ configuration
+
+ -
+ Make it work: see
+ https://lwn.net/Articles/454795/
+ and send proposal to debian-kernel
+
+
+
+

New KMS drivers [3.3-3.10]
+
+ -
+ DRM/KMS drivers added for old, new and virtual hardware -
+ AST, DisplayLink, Hyper-V, Matrox G200, QEMU Cirrus
+
+ -
+ Should be more robust than purely user-mode drivers, and
+ compatible with Secure Boot
+
+ -
+ Current X drivers don't work with these, so the kernel drivers
+ are disabled for now
+
+ -
+ Make it work: join the X Strike Force and package the new X
+ drivers
+
+
+
+

Module signing [3.7]
+
+ -
+ Kernel modules can be signed at build time, and the kernel
+ configured to refuse loading unsigned modules
+
+ -
+ Necessary but not sufficient to implement Secure Boot -
+ we would also need signed kernel images and some other
+ restrictions when booted in this mode
+
+ -
+ Make Secure Boot work: come to the meeting on Tuesday
+

More support for discard
+
+ -
+ Flash devices (and thin-provisioned SANs) can be more efficient
+ if the filesystem 'discards' unused disk space
+
+ -
+ Requires support in hardware, driver, filesystem and any layered
+ device drivers - e.g. LVM, RAID (added in 3.7)
+
+ -
+ Must be explicitly enabled, but d-i doesn't do this by default
+
+ -
+ Make it work: fix http://bugs.debian.org/690977
+
+
+
+
+
+
User namespaces [3.7]
+
+ -
+ One of the last missing pieces for OpenVZ-like containers
+
+ -
+ Each user namespace has its own root user with
+ privileges over the users and processes in that namespace - but
+ not the whole system
+
+ -
+ Currently somewhat experimental, and requires filesystem
+ changes which haven't been done for XFS
+
+ -
+ Make it work: send patches to upstream XFS developers (this
+ one's hard)
+
