Currently the nvme driver will always log any

applications may not want this behavior. So provide
an option to disable it at the controller level.
When this option is enabled, any failed requests
from queues associated with that controller
(including the admin queue) will not log the
failed request.
Of course the application will still receive
the failed status code and can decide to do its

how we allocated and freed both the pool and the mbufs.
This also fixes an issue that I hadn't addressed yet with freeing
chained mbufs. Use of the mbuf macro to free them instead of the
generic spdk functions takes care of that for us.

We have observed unexpcted timeout when we remove LUNs from the
active iSCSI target dynamically during FIO workload.
By making destroy_raid_bdev RPC wait for its completion, we could know
the destroy_raid_bdev RPC caused timeout because LUN hot removal didn't
complete.
By investigating the log, incoming I/Os from the host had not stopped
even after hot removal process was started.
The reason was that iSCSI target had continued to accept incoming I/Os
from the host.
By removing LUN from the SCSI device at the start of the LUN hot removal
process, iSCSI target will be able to stop incoming I/Os and LUN hot removal
will complete in finite time.
LUN itself can be accessible even after it is removed from the SCSI device.
LUN hot removal is for not I_T nexus but I_T_L nexus and so we cannot
start connection exiting in this case because connection can have multiple
LUNs. So this fix requires few changes and will be practical.
