Squash changes for _bdevperf_construct_targets() and
bdevperf_free_targets() into a single patch to shrink the
patch series to reduce the burden of reviewers.
The pupose of the whole patch series is to move io_target from
core based to I/O channel based, and create SPDK thread per I/O channel.
It was not possible to create SPDK thread per core and then associate
target group with I/O channel as long as I tried.
So this patch moves io_target from core based to I/O channel based.
The later patch will create SPDK thread per I/O channel.
Each core has default reactor thread for now and so we can use
spdk_for_each_channel() even when we do not create and destroy SPDK
thread per target group yet.
The following is the detailed explanation:
_bdevperf_construct_targets():
Add a context for _bdevperf_construct_targets() to use
spdk_for_each_channel().
If g_every_core_for_each_bdev is false, set the target group to the
context and create target only on the group which matches the passed
group. If g_every_core_for_each_bdev is true, create target on all
groups.
Only the master thread can increment g_target_count. Hence hold
created number of targets temporary on the context and add it at
completion.
As a result of these changes, spdk_bdev_open() is called on the
thread which runs I/O to the bdev.
Hence bdevperf_target_gone() doesn't use message passing, and
bdevperf_complete() calls spdk_bdev_close() before sending
message to the master thread. Additionally, unregister pollers
directly in bdevperf_target_gone().
These changes also fix the potential issue that spdk_bdev_close()
would be called on the wrong thread if spdk_bdev_get_io_channel()
fails in bdevperf_submit_on_group().
bdevperf_free_targets():
Free each target on the thread which created it by using
spdk_for_each_channel().
This will make possible for us to use spdk_for_each_channel() for
performance dump even for shutdown case because
spdk_for_each_channel() is serialized if it is called on the same
thread.

shifted, so that each time the function is called a subsequent IO

This is the first patch of a series that replaces single global write
buffer with per-io_channel buffers. This change is intended to improve
performance for multithreaded workloads.
This patch changes the way the ftl_io_channels are allocated by only
keeping an ftl_io_channel pointer inside spdk_io_channel's context. It
allows for delaying IO channel destruction, which in turn allows the FTL
to iterate over all exisiting IO channels without locking.

Follow the idea of bdev_get_iostat in module/bdev/rpc/bdev_rpc.c.
Add a global variable g_bdev_count and then set it to 1 as sentinel
value in bdev_construct_targets().
Subsequent patches will make _bdevperf_construct_targets() asynchronous.
Then bdevperf_construct_targets() will be truely asynchronous.
This patch is too small to be an independent patch but keep to
hold previous review result.

Add a flag resched to check if reschedule operation is requested
to struct spdk_lw_thread. Add _reactor_resquest_thread_reschedule()
to set the resched flag, and add it to the case SPDK_THREAD_OP_RESCHED
in spdk_reactor_thread_op(), and return true in the case
SPDK_THREAD_OP_RESCHED in spdk_reactor_thread_op_supported().
Then _spdk_reactor_run() checks if the resched flag is true for each
thread. If true, set the resched flag to false, and remove the
thread and call _reactor_schedule_thread(). Add continue to avoid
use-after-free issue for both reschedule and terminate cases.
This idea follows voluntary thread termination and will remove our
worries for all complicated rare cases.
Add unit test case to verify this update.
