2010-10-22: kernel 2.6.36 - upstream (feature description)

To download the linux-2.6.36.tar.gz visit: //www.kernel.org/pub/linux/kernel/v2.6

Since kernel 2.6.35, no more kernel kerntypes-patches (required for work with lcrash, from lkcdutils/LKCD) are provided: Use crash instead of lcrash.

The upstream kernel 2.6.36 contains the following functionality developed by the Linux on System z development team:

cio, zfcp: Logging I/O subchannel status information
In case of severe errors for an FCP channel, zfcp triggers a set of log entries with I/O subchannel status information, useful for support specialists analyzing the situation.

Note that this functionality is available on z10 since November 2009.

Note that this functionality is not available when Linux on System z is running as a guest under z/VM.

dasd: Tunable default grace period for missing interrupts in DASD
If a storage server does not respond to an I/O request within a given timeout period (kernel-default depending on the type of DASD), Linux considers the request failed and cancels it. This feature provides a user interface to specify the timeout for missing interrupts for standard I/O operations.

kernel: Enable support for "event triggers" HBA_GetEventBuffer()
zfcp HBA API 2.1 requires kernel 2.6.36 to handle HBA_GetEventBuffer() correctly.

2010-10-22: "Development Stream" kernel 2.6.36 message catalog (feature - optional patch)

linux-2.6.36-s390-message-catalog.tar.gz / MD5 ... recommended (2010-10-22)

This patch contains:

Kernel message catalog.
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'.
