Hello,
This series supports namespace attachment: attach and detach. This is
the second version series with a fix a bug on choosing a controller to
attach for a namespace in the attach command handler.
Since V1:
- Fix to take 'ctrl' which is given from the command rather than 'n'.
(Klaus)
- Add a [7/7] patch to support CNS 12h Identify command (Namespace
Attached Controller list).
This series has been tested with the following: (!CONFIG_NVME_MULTIPATH)
-device nvme-subsys,id=subsys0 \
-device nvme,serial=foo,id=nvme0,subsys=subsys0 \
-device nvme,serial=bar,id=nvme1,subsys=subsys0 \
-device nvme-ns,id=ns1,drive=drv0,nsid=1,subsys=subsys0,zoned=false \
-device nvme-ns,id=ns2,drive=drv1,nsid=2,subsys=subsys0,zoned=true \
-device
nvme-ns,id=ns3,drive=drv2,nsid=3,subsys=subsys0,detached=true,zoned=false \
-device
nvme-ns,id=ns4,drive=drv3,nsid=4,subsys=subsys0,detached=true,zoned=true \
