* '''Comments''': Per the oneiric review, The module is needed to activate RAID4 and RAID5 configurations with dmraid (package). This reads the meta-data created by BIOS supported soft-RAID implementations and creates device-mapper targets. Upstream indicated that the dm-raid45 module is seen as deprecated and dm-raid (a RAID 4/5/6 target) would be the replacement. However currently available versions of the user-space application do not support this. The difference between both targets is substantial from the point of table formats. This means to create a mapping with the new target the user-space side has to change substantially. So currently we will need to go with the old module. 1. fsam7400 - SW RF kill switch for Fujitsu Siemens Amilo M 7400 / Maxdata 7000DX and compatible hardware. 1.

Summary
Release Note
Review of the current Ubuntu Kernel patch delta from upstream. This session will look at the current delta comprised of both patches to the core and the ubuntu specific drivers. The aim is to record what we are carrying, review the reasons for that component(s) to be carried, and recommend replacements, updates, cleanups, upstreaming etc of those components.
Rationale
All patches and drivers carried in the Ubuntu delta are not automatically sync'd with the upstream kernel for various reasons. This places a maintenance burden on the Ubuntu kernel team. These patches and drivers must be regularly reviewed to determine if they are still needed, if they need updating to a later version, or if they are now ready for upstream acceptance. The purpose of this blueprint is to facilitate and record this review for the P cycle.
This review is based on the the latest Precise kernel 3.1.0-2.2 release (which was rebased onto upstream v3.1 final). The delta at this point is as follows:
# patches |
comment |
346 |
patches on top of the v3.1 kernel |
107 |
SAUCE patches |
131 |
debian commits (configuration updates and build machinary) |

Comments: Per the oneiric review, The module is needed to activate RAID4 and RAID5 configurations with dmraid (package). This reads the meta-data created by BIOS supported soft-RAID implementations and creates device-mapper targets. Upstream indicated that the dm-raid45 module is seen as deprecated and dm-raid (a RAID 4/5/6 target) would be the replacement. However currently available versions of the user-space application do not support this. The difference between both targets is substantial from the point of table formats. This means to create a mapping with the new target the user-space side has to change substantially. So currently we will need to go with the old module.
