Also change type and status from enums (needing 4 bytes)
to int16_t which is still a far bigger range than
needed.
Next, modify spdk_bdev_get_io to only zero the
first cacheline (actually a bit less).
SPDK_BDEV_IO_TYPE_INVALID is also added, making it
explicit that 0 is an invalid value for the IO type.
Previously this was somewhat inferred.
There are still additional improvements that can

We no longer support resubmitting an existing I/O to
a lower bdev. This enables accurate tracking of I/O
at each bdev layer for purposes of reset handling and
QoS.
__submit_request() in bdev.c is now only called
from spdk_bdev_io_submit(), so just collapse these
two functions together while we are here.

This follows similar recent changes to bdev/split.
Future patches will move quite a bit of duplicated
code between these modules to a set of helper functions,
so doing this renaming will make those future patches

split, gpt and error all have a lot of similar code, and
are based on the presumption of one or more "partition" bdevs
on a "base" bdev. This results in quite a bit of duplicated
code between these three bdev modules. The error bdev
module does follow this same model - it just always has only
a one-to-one mapping between the error bdev and its base bdev.
As all of the modules move to allocating their own bdev_io
rather than allowing for adjusting an existing bdev_io and
resubmitting it, there will be even more duplicated code
between these modules.
So this patch adds a set of helper functions in the common
bdev library to eliminate all of this duplicated code.
This patch also moves the split module to use it - future
patches will also convert gpt and error.

rte_vhost: received SET_VRING_BASE message,
calling destroy_device() as usual
user: end-user asks to remove the device (together with socket file),
OK, device is not *in use* - that's NOT the behavior we want

Instead of changing new_device/destroy_device callbacks and breaking

2 locks are executed in 2 places in opposite orders.
Consider the following scenario, threads A and B:
(A)
* fdset_event_dispatch() start
* pfdentry->busy = 1; (lock #1)
* vhost_user_read_cb() start
* vhost_destroy_device() start
(B)
* rte_vhost_driver_unregister() start
* pthread_mutex_lock(&vsocket->conn_mutex); (lock #2)
* fdset_del()
* endless loop, waiting for pfdentry->busy == 0 (lock #1)
(A)
* vhost_destroy_device() end
* pthread_mutex_lock(&vsocket->conn_mutex); (lock #2)
(mutex already locked - deadlock at this point)
Thread B has locked vsocket->conn_mutex and is in while(1)
loop waiting for given fd to change it's busy flag to 0.
Thread A would have to finish vhost_user_read_cb() in order
to set busy flag back to 0, but that can't happen due to
the vsocket->conn_mutex lock.
This patch defers the fdset_del(), so that it's called outside of
vsocket->conn_mutex.

at a higher priority than attempting to look up

Further, rte_mem_virt2phy() will always fail when

Previously, the shared buffer pools were allocated on the
nvmf controllers. When a new connection was established,
the CONNECT command needs a 4k buffer, but we didn't know
which nvmf controller it belonged to until after the
CONNECT command completed. So there was a special case
for CONNECT that used in capsule data buffers instead.
Now, the buffer pool is global and always available. We
can just use that always, with no more special cases.
This has the additional nice side effect of allowing
users to run the target with no in capsule data buffers
allocated at all.

An optional field was added in NVMe 1.3 to indicate the optimal I/O
boundary that should not be crossed for best performance. This is
equivalent to the existing Intel-specific stripe size quirk.
Add support for the new NOIOB field and move the current quirk-based
code so it is updated in nvme_ns_identify_update().

There is one scenario, when one large read IO is splitted into several
subtasks 1 - N, and the subtask N return successful, it will be stored
in the subtask_list of primary task, but the other tasks could return
error, then when we try to return the subtask N, it will failed, this patch
will make sure the large read IO command return correctly if any of the
subtasks failed.

The Linux kernel NVMe-oF target can easily be misconfigured to report
newline-terminated strings from the discovery service, since its
parameters are set by echoing into sysfs files, and echo adds a newline
by default.
Newline characters are not allowed as part of the TRADDR and TRSVCID
fields, since they are defined as ASCII strings in the NVMe specification
sense, which limits the acceptable characters to the 0x20-0x7E range.
However, we can add a workaround for misconfigured targets with trailing
newlines that shouldn't impact any valid configurations.

spdk_iscsi_transfer_in() after all the other subtaks, but when the N - 1 subtask
return from function spdk_iscsi_transfer_in(), it meet the condition:
primary->bytes_completed == primary->scsi.transfer_len
then it will send response pdu, after this, the primary task return from
spdk_iscsi_transfer_in(), it also meet the condition, so it will also try
to send response pdu, this will make the application run into error.

Hotremove event was detected on base bdev, but wasn't propagated to
vbdevs. This patch makes base bdev destroy all it's children once
hotremove is triggered. This fixes hotremove segfaults and adds full
support for split/gpt hotremove.

Unregistering a device should be deferred if I/O

undergoing a deferred unregister themselves.

Add a new struct spdk_nvme_io_qpair_opts to allow the user to override
controller options on a per-I/O qpair basis.
Existing callers with qprio == 0 can be updated to:
... = spdk_nvme_ctrlr_alloc_io_qpair(ctrlr, NULL, 0);
Callers that need to specify a non-default qprio should be updated to:
struct spdk_nvme_io_qpair_opts opts;
spdk_nvme_ctrlr_get_default_io_qpair_opts(ctrlr, &opts, sizeof(opts));
opts.qprio = SPDK_NVME_QPRIO_...;

When device has more than one open descriptor, remove_cbs of particular
descriptors could be called more than once.
Consider the following scenario:
bdev X with 2 open descriptors A and B.
X is removed (hotremoved for instance)
bdev_unregister(X) is called
* bdev->status = REMOVING
* A->remove_cb is called
* some poller is started
* B->remove_cb is called
* another poller started
* poller from A->remove_cb finishes it's work and closes the desc:
* bdev_close(A)
* A is removed from bdev->open_descs list
* bdev->status is REMOVING, so bdev_unregister(X) is called again!
* B->remove cb is called again!
* another poller starts? segfault?
