v6: Fix the cleaning up around nvme_init() and write cache setup in
nvme_file_open(). [Stefan]
Add Stefan's rev-by to the doc patch.
Rebase on to Paolo's coroutine series for q->free_req_queue:
Based-on: 20180115220822.10156-1-pbonz...@redhat.com
([PATCH 0/4] coroutine-lock: polymorphic CoQueue)
v5: Add Stefan's rev-bys.
Add Paolo's sob line.
Address Stefan's, Alex's and Eric's comments, including:
- Add PCI Bar MMIO offset/size parameter to VFIO utility API. [Alex]
- Fix various lock and memory leakings. [Stefan]
- Improve documentation. [Stefan]
- Add one missing "Since 2.12" in QAPI schema. [Eric]
- Fix locking of BDRVNVMeState->inflight. [Stefan]
- Add one missing endianness conversion for cmd.nsid. [Stefan]
- Use bdrv_get_aio_context() instead of qemu_get_current_aio_context().
- When init, issue "Set Features" command to enable/disable volatile write
cache according to "flags & BDRV_O_NOCACHE".
v4: - Rebase, address Stefan's comments.
- Add QAPI and doc patches.
v3: Rebase, small tweaks/fixes and add locks to provide basic thread safety
(basic because it is not really tested).
v2:
- Implement "split vfio addr space" appraoch. [Paolo]
- Add back 'device reset' in nvme_close(). [Paolo]
- Better variable namings. [Stefan]
- "Reuse" macro definitions from NVMe emulation code.
- Rebase onto current master which has polling by default and update
performance results accordingly.
- Update MAINTAINERS.
- Specify namespace in URI.
- The sporadical I/O error from v1 "disappeared" in this version.
- Tests one: qemu-img bench, fio, bonnie++ and installation of
ubuntu/fedora/rhel on QEMU emulated nvme and a Intel P3700 card.
