Hello,
here are 5 patches, which cleanup the I2O subsystem in 2.6.
The patches are as follows:
- i2o-config-clean.patch
* Changes the formating of the header in i2o_config.c
- i2o-passthru.patch
* Add a pass-thru ioctl to i2o_config, which is needed to work with
the Adaptec management software.
- i2o_block-cleanup.patch
* more than 3 "visible" disks (hda, hdb, hdc, hdd) lead to kernel
panics.
* removes some unused code with partitions.
* I2O_LOCK was often called with the addresses of the controller, and
not with the address of the device. Fixed.
* the cleanup function for gendisk (del_gendisk) doesn't work if the
queue is shared between different devices. To workaround the queue
is removed before.
* redundant code removed in module initialization and remove, use
i2ob_new_device and i2ob_del_device instead.
* removed atomic_t queue_depth
* removed unnecessary and bogus code for queue handling
- i2o-64-bit-fix.patch
* provides i2o_context_list_*() functions, which maps 64-bit pointers
to 32-bit context id's in a dynamic list. On 32-bit systems the
functions are replaced with a static inline.
* i2o_scsi now uses the i2o_context_list_*() functions for transaction
context, and therefore now work on 64-bit systems too.
- i2o-makefile-cleanup.patch
* The Kconfig and Makefile in drivers/message/i2o still got a
CONFIG_I2O_PCI entry, which is not used anymore. This one is
replaced by a CONFIG_I2O_CONFIG entry, which now builds the
i2o_config module.
Already posted the first 4 patches to linux-scsi with request for
review, but expect of the i2o-passthru.patch there where no complains.
And the request for using the SG_IO in i2o-passthru.patch isn't possible
at the moment, because it is a char device node.
If you have any questions / problems, please let me know.
Best regards,
Markus Lidel

Sounds like a good reason to completly kill the macro while we're at it.

Yep, you are right. The patch complety removes the macro.
