For 3.10-3.13 this patch works, but for 3.4 I get the build error:

ERROR: "dm_kobject_release" [drivers/md/dm-mod.ko] undefined!
/ssd/gregkh-linux/stable/linux-3.4.y/scripts/Makefile.modpost:91: recipe for target '__modpost' failed
make[1]: *** [__modpost] Error 1

So I'm dropping it from that branch.  Care to send me a version that
builds properly for that kernel release?

thanks,
