3e7394af6a bdev: remove bdev_register_examine_thread deprecation
Starting in SPDK 23.01, calling spdk_bdev_register() and
spdk_bdev_examine() from a thread other than the app thread was
deprecated. This commit removes the deprecation and as such calling
these functions from a thread other than the app thread is an error.

As a side effect of this commit, all bdev module examine_config() and
examine_disk() callbacks will be called on the app thread.

3522d43a95 bdev: Unify _resize_notify() and _remove_notify()
The next patch will improve media mgmt notifications but it will be
almost same as _resize_notify() and _remove_notify().

On the other hand, there are a few differences between _resize_notify()
and _remove_notify(). _remove_notify() will be better.

To avoid duplication, unify _resize_notify() and _remove_notify() by
adding abstraction event_notify() and _event_notify().

Add unit tests for the complex race conditions.

cf64422ad7 bdev: call unregister callback on correct thread
We should always called the unregister callback on
the same thread that spdk_bdev_unregister() was
originally called.  So save the thread pointer and
use an spdk_thread_send_msg() to make sure it gets
called on the correct thread when the unregister
finishes.

Also add unit test that reproduces the original
issue.

Fixes issue #2883.

a6e58cc44c bdev: examine and register on app thread
This introduces a deprecation for calling spdk_bdev_register() and
spdk_bdev_examine() on a thread other than the app thread. The
deprecation period starts in SPDK 23.01 and removal is expected in SPDK
23.05.

The intent of this deprecation is to ensure that bdev modules'
examine_config() and examine_disk() callbacks are only ever called on
the app thread. This largely a formalization of what has long happened
due to the RPC poller running on the first thread started by
spdk_app_start().

interface.

To make sure we respect spdk_bdev_opts's (small|large)_buf_pool_size, we
call spdk_iobuf_set_opts() from spdk_bdev_set_opts().  These two options
are now deprecated and users should switch to spdk_iobuf_set_opts().

a6dbe3721e update Intel copyright notices

git log --follow -C90% --format=%ad --date default <file> | tail -1

and then pull just the 4 digit year from the result.

Intel copyrights were not added to files where Intel either had
no contribution ot the contribution lacked substance (ie license
header updates, formatting changes, etc).  Contribution date used
"--follow -C95%" to get the most accurate date.

Note that several files in this patch didn't end the license/(c)
block with a blank comment line so these were added as the vast
majority of files do have this last blank line.  Simply there for
consistency.

A new parameter io_drain_timeout has been added to spdk_bdev
structure. If this value is unset, the bdev reset behavior
does not change.
The io_drain_timeout controls how long a bdev reset must wait for IO
to complete prior to issuing a reset to the underlying device.
If there is no outstanding IO at the end of that period, the reset
is skipped.

488570ebd4 Replace most BSD 3-clause license text with SPDX identifier.
Many open source projects have moved to using SPDX identifiers
to specify license information, reducing the amount of
boilerplate code in every source file.  This patch replaces
the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause
identifier.

Almost all of these files share the exact same license text,
and this patch only modifies the files that contain the
most common license text.  There can be slight variations
because the third clause contains company names - most say
"Intel Corporation", but there are instances for Nvidia,
Samsung, Eideticom and even "the copyright holder".

Used a bash script to automate replacement of the license text
with SPDX identifier which is checked into scripts/spdx.sh.

7bcd316de1 bdev: abort all IOs when unregistering the bdev
To fix issue: #2484

When unregistering the bdev, will send out the message
to each thread to abort all the IOs including IOs from
nomem_io queue, need_buf_small queue and need_buf_large queue.

The new SPDK_BDEV_STATUS_UNREGISTERING state is newly
added to indicate this unregister operation.

In this case, the bdev unregister operation becomes the
async operation as each thread will be sent the message
to abort the IOs and as the last step, it will unregister
the required bdev and associted io device.

On the other hand, the queued_resets will be handled
separately and not aborted in the bdev unregister.

New unit test cases are also added:
  enomem_multi_bdev_unregister: to abort the IO from
nomem_io queue during the unregister operation
  bdev_open_ext_unregister: to handle the events and
async operations from the unregister operation

494eb6e58b bdev: Fix race among bdev_reset(), bdev_close(), and bdev_unregister()
There is a race condition when a bdev is unregistered while reset is
submitted from the upper layer very frequently.

spdk_io_device_unregister() may fail because it is called while
spdk_for_each_channel() is processed.

    spdk_io_device_unregister io_device bdev_Nvme0n1 (0x7f4be8053aa1)
    has 1 for_each calls outstanding

To avoid this failure, defer calling spdk_io_device_unregister() until
reset completes if reset is in progress when unregistration is ready
to do, and then reset completion calls spdk_io_device_unregister()
later.

A bdev cannot be opened if it is already deleting. So we do not need
to hold mutex.

By using this, add a helper function bdev_abort_queued_io(), and
change _bdev_io_submit() to call bdev_abort_queued_io(), and
call _bdev_io_complete_in_submit() with success if bdev_abort_queued_io()
returned true when QoS is enabled on the corresponding channel.
Add necessary unit test together.

Update unit test accordingly, especially, update stub_submit_request()
to abort the matched I/O, update io_during_io_done() because we need to
know not boolean but the exact completion status now, and update
basic_qos() to reset the rate limit to test the abort I/O feature.

ebd1a4f76c bdev: inherit locked ranges for new channels
Keep a mutex protected list of the active locked ranges
in the bdev itself.  This is only accessed when a new

the currently locked ranges.

b90b7ce477 bdev: queue new IO that overlap a locked region
Add an io_locked TAILQ to each channel, which hold
IO that will write to a currently locked region.

Also add a new step to the locking process per channel.
Each channel needs to wait until all existing outstanding
writes to the newly locked range have been completed.

Only the channel that locked an LBA range may submit
write I/O to it.  It must use the same cb_arg for the
write I/O as the cb_arg used when locking the LBA range.
This ensures that only the specific I/O operations needing
the lock will bypass the lock.

When a range is unlocked, we will just blindly try to
resubmit all IO in the io_locked tailq.  This could be
made more efficient in the future, but we don't expect
this path to occur very often, so going for simplicity
in the first pass.

283abcb9a2 bdev: temporarily allow bdev descriptors to be closed from any thread
Bdev descriptors could be closed only from the same thread
that opened them. This restriction was suddenly introduced
at one point without making sure all the SPDK code respects
it. Vhost can still close descriptors from any arbitrary
thread and fixing that would require some more effort.

With this patch we remove the thread-specific assert from
spdk_bdev_close() and hence allow vhost to work properly
in debug builds. Vhost can still have a possible data
race with bdev hotremove notification, but let's get rid
of the abort() from the usual code path first.

f93b6fb0a4 bdev: defer unregister untill *all* descriptors are closed
We used to wait only for those descriptors which
specified the hotremove notification callback. The
bdev could've been removed before the descriptor
was closed and the subsequent spdk_bdev_close would
simply segfault.

This patch modifies spdk_bdev_unregister to always
wait for all descriptors to be closed before actually
unregistering the bdev. This consolidates the bdev
unregister behavior for descriptors with and without
the hotremove callback.

df6b55fd8c bdev: make spdk_bdev_register_module_xxx function names predictable
Currently, the SPDK_BDEV_REGISTER_MODULE() macro uses __LINE__
to generate functions like spdk_bdev_module_register_187().

Typically, this is not a problem as these functions are not called directly
rather, they are only used as constructor functions to load the bdevs during
system startup.

There are languages however, (e.g rust) that require these functions to be
referenced explicitly to prevent them from being removed during the linking phase.

In order to reference them, having the names predictable (and potentially
changed per commit) makes things easier.
