Subject[PATCHSET 0/5 v2] brd: partition fixes
Jens Hi

What do you intend to do with these fixes? 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
