2. Driver and architecture-specific changes

All the driver and architecture-specific changes can be found in the [http://kernelnewbies.org/Linux_3.2_DriverArch Linux_3.2_DriverArch page]

3. VFS

• The i_mutex lock use of generic _file_llseek hurts. Do (nearly) lockless generic_file_llseek [http://git.kernel.org/linus/ (commit)]

4. Memory management

• slub: per cpu cache for partial pages [http://git.kernel.org/linus/ (commit)]

• slub: update slabinfo tools to report per cpu partial list [http://git.kernel.org/linus/ (commit)]

5. Networking

• Add netlink based CAN routing [http://git.kernel.org/linus/ (commit)]

• Add ethtool -g support to virtio_net [http://git.kernel.org/linus/ (commit)]

* Batman adhoc networking

implement AP-isolation on the receiver side [http://git.kernel.org/linus/ (commit)], implement AP-isolation on the sender side [http://git.kernel.org/linus/ (commit)]

• af-iucv: The current transport mechanism for af_iucv is the z/VM offered communications facility IUCV. To provide equivalent support when running Linux in an LPAR, HiperSockets transport is added to the AF_IUCV address family [http://git.kernel.org/linus/ (commit)]
