Cover letter [PATCH 0/3] NVMe: Introduce CMB allocation scheme
Applies to Jens' for-4.5/nvme
This patchset changes the CMB allocation scheme. Instead of reserving the entire range for SQes and automatically placing the SQes in the CMB, this set creates sysfs knobs to manage it. This allows partial usage of the CMB for SQes, so that the remainder can be mmapped or used for other NVMe-defined CMB usages.
