Hi all, this series tries to remove two abuses of the get_gendisk API. The first one is fairly straigt forward and switched the blk-cgroup configuration API to properly open the block device, but I'd love to see it reviewed and tested by the cgroup maintainers, as I don't really know how this code is actually used.
The other one in the hibernation code really puzzles me - it busy loops on the gendisk lookup, just to leak a reference when it finally succeeds and then doesn't actually do anything with the result. My proposal for now is to simply revert the offending change, but better proposals are welcome.
