These are real bugs on devices shipped for a while now. I think they need to go into current 3.17-rcX Kernel. If not then lets please put them in for-next [This set is for linux-block.git/for-next, tell me if you need one ontop of for-linus] [v2] Based on Jens's linux-next [30e996a] incorporating the brd patch by Dmitry Monakhov. Dmitry has introduced a new part_show parameter, this parameter is now removed and we always "part_show=1". Scripts that did part_show=1 will work just the same but will display a message in logs. This is harmless. (And scripts can be modified to remove this parameter) [v1] Current situation is that any attempt to use partitions with brd device would create the partition but then any use will trash the data. See: http://www.spinics.net/lists/linux-scsi/msg76737.html So these patches fixes up all the problems we saw with the code, but not sacrificing any of the old fixtures. See [patch 4/5] for more explanations. list of patches: [PATCH 1/5] axonram: Fix bug in direct_access [PATCH 2/5] Change direct_access calling convention These are Matthew's patches from the DAX series which fixes the interface to direct_access taking into account the partition offset. It must be applied here for partitions to work with direct_access() API. [PATCH 3/5] brd: Add getgeo to block ops This one is needed by fdisk, otherwise it just asks extra questions [PATCH 4/5] brd: Fix all partitions BUGs [PATCH 5/5] brd: Request from fdisk 4k alignment Thanks Boaz
