2009-09-23: kernel 2.6.31 - upstream (feature description)

To download the linux-2.6.31.tar.gz visit: http://www.kernel.org/pub/linux/kernel/v2.6

The upstream kernel 2.6.31 contains the following functionality developed by the Linux on System z development team:

Summary:
af_iucv: datagram sockets
Description:
In addition to the existing stream-oriented af_iucv sockets (SOCK_STREAM) another af_iucv socket type is offered:

Summary:
kernel: Suspend/Resume (hibernate) support
Description:
Suspend/Resume is a feature where the main memory of a running Linux on System z instance (running in LPAR or as a z/VM guest) is written to disk before shutting Linux down.

When the Linux instance is restarted, the memory contents is reloaded and the Linux on System z instance is restored to the state it was in when the suspend operation was invoked.


Summary:
zfcp: Variable queue depth in zfcp driver
Description:
zfcp as SCSI low-level-driver in Linux reports the number of commands that can be issued to a SCSI device at the same time. Up until now this number was 32 with no way to change it.

This enhancement provides a new kernel parameter zfcp.queue_depth to change the queue depth for new SCSI devices and makes the queue_depth parameter in SCSI devices writable to change the queue depth for already existing SCSI devices.

2009-09-23: "Development Stream" kernel 2.6.31 kerntypes (feature - optional patch)

linux-2.6.31-s390-kerntypes.tar.gz / MD5 ... recommended (2009-09-23)

This patch contains:

Summary:
Kernel types for lcrash dump analysis.
Description:
Add a dummy module that contains all relevant kernel types that the dump analysis tool lcrash needs. The kernel type information is used as input by the lcrash utility when analysing system crash dumps or the live system.

This patch is optional as it is very unlikely to be accepted in upstream kernel, but is recommended for all distributions which are built based on the 'Development stream'.

2009-09-23: "Development Stream" kernel 2.6.31 message catalog (feature - optional patch)

linux-2.6.31-s390-message-catalog.tar.gz / MD5 ... recommended (2009-09-23)

This patch contains:

Summary:
Kernel message catalog.
Description:
Add support for automatic message tags to the printk macro families dev_xyz and pr_xyz. The message tag consists of a component name and a 24 bit hash of the message text. For each message that is documented in the included kernel message catalog a man page can be created with a script (which is included in the patch). The generated man pages contain explanatory text that is intended to help understand the messages.

Note that only s390 specific messages are prepared appropriately and included in the generated message catalog.

This patch is optional as it is very unlikely to be accepted in upstream kernel, but is recommended for all distributions which are built based on the 'Development stream'.
