db8bd99588 bdev/part: Add spdk_bdev_part_base_construct_ext() to pass bdev_name
Add an new API spdk_bdev_part_base_construct_ext() to pass not bdev but
bdev_name to fix the race condition due to the time gap between
spdk_bdev_get_by_name() and spdk_bdev_open(). A pointer to a bdev is
valid only while the bdev is opened.

In the new API, spdk_bdev_get_by_name() is included in
spdk_bdev_part_base_construct_ext() and the caller has to know if
the bdev exists or not. Hence spdk_bdev_part_base_construct_ext()
returns return code and returns the created part object by the double
pointer.

Another critical change is that base is just freed if spdk_bdev_open_ext()
failed with -ENODEV. The reason is that if we call spdk_bdev_part_base_free()
for that case, the configuration is removed by the registered callback
and so bdev_examine() will not work.

The following patches will replace spdk_bdev_part_base_construct()
by spdk_bdev_part_base_construct_ext() for the corresponding bdev
modules.

c59f0022c3 bdev/part: Use spdk_bdev_open_ext() instead of spdk_bdev_open()
This is just a drop in replacement of spdk_bdev_open().

Hold the passed remove_cb in struct spdk_bdev_part_base, and use
it in the new callback function bdev_part_base_event_cb. The resize
event is not supported for now.

b3be320de4 vbdev: close the base bdev on its opened thread
With the JSON configure, the base device will be opened on the
same thread (RPC thread) to handle the JSON operation. Later the
virtual device upon the base device can be opened on another
thread. At the time of virtual device destruction, the base
device is also closed at the thread where opening the virtual
device, it is actually different than the original thread where
this base device is opened through the JSON configure.

Add a thread here to record the exact thread where the base
device is opened and then later route it back to handle the base
device close operation.

1384ad007c module/bdev: add zcopy abilities to virtual bdevs.
These bdevs claim native support for zcopy operations. They should
actually support them when running on top of a bdev that claims zcopy
support.

For example, if you were to build a part or passthru bdev on top of a
malloc_bdev (which is just for testing primarily) and then try to run
bdevperf on top of that, you will currently get errors. This patch fixes
that problem.

4368937b4e bdev/part: remove thread safety from part_construct()
spdk_bdev_part_construct() must be now called on the
same thread that called spdk_bdev_part_base_construct().

This was always the case so far and I don't see any other
case where thread safety could be useful, so just remove
it. The doxygen doesn't say anything about it either.

Even in GPT case, we create a base directly as a part of
examine and then create part bdevs in the spdk_bdev_read()
completion callback, but that callback will be always
executed on the same thread which issued the read.

bfd1e46e6e bdev: deprecate spdk_vbdev_register
This API had good intentions, but as more complicated
use cases came up where base bdevs could come and go,
we've realized that the bdev layer will need another
mechanism to query bdev modules on these types of
relationships between a virtual bdev and its base
bdevs.  We removed all code related to tracking
the array of base bdevs a long time ago.

Change all existing callers to use spdk_bdev_register.
Document spdk_vbdev_register as deprecated for now,
and change its implementation to just call
spdk_bdev_register for simplicity sake.

tightly associated with the part base, which can be

bcff4c89b8 bdev: Rename spdk_internal/bdev.h to spdk/bdev_module.h
This will become the public interface for implementing
bdev modules. Right now the file exposes too much of
the guts of the bdev layer to modules, so it needs
to be stripped down.

19100ed580 bdev: rename spdk_bdev_module_if -> spdk_bdev_module
This better matches the style in the rest of SPDK.

No functional change - this is a pure find/replace of
spdk_bdev_module_if to spdk_bdev_module.  Instances of this struct will
be renamed in another patch.
