Hi all,
I've rebased the patch on top of Jens' for-linus and Matthew's master. The patch now applies cleanly when submitted upstream.
The bug reports seem to have calmed down. Ming reported a double completion bug that is fixed in Jens' for-linus tree. We should be able to flesh out any outstanding bugs in the 3.16-rc cycles.
Jens for-linus up to:
2b8393b43ec672bb263009cd74c056ab01d6ac17 blk-mq: add timer in blk_mq_start_request
Matthew master up to:
bd67608a6127c994e897c49cc4f72d9095925301 NVMe: Rename io_timeout to nvme_io_timeout
The merged trees with the patch on top is found here:
