lib/bdev: Add spdk_bdev_abort API
Add spdk_bdev_abort function as a new public API.
This goes all the way down to the bdev driver module and attempts to
abort all I/Os which has bio_cb_arg as its callback argument.
We can separate when only a single I/O has bio_cb_arg and when multiple
I/Os have bio_cb_arg, but unify both by using parent - children I/O
relationship. To avoid confusion, return matched_ios by _bdev_abort() and
store it into split_outstanding by the caller.
Exclude any I/O submitted after this abort command because the same cb_arg
may be used by all I/Os and abort may never complete.
bdev_io needs to have both bio_cb_arg and bio_to_abort because bio_cb_arg
is used to continue abort processing when it is stopped due to the capacity
of bdev_io pool, and bio_to_abort is used to pass it to the underlying
bdev module at submission. Parent I/O is not submitted directly, and is
only used in the generic bdev layer, and parent I/O's bdev_io uses bio_cb_arg.
Hence add bio_cb_arg to bdev structure and add bio_to_abort to abort structure.
In the meantime of abort operation, target I/Os may be completed. Hence
check if the target I/O still exists at completion, and set the completion
status to false only if it still exists.
Upon completion of this, i.e., this returned zero, the status
SPDK_BDEV_IO_STATUS_SUCCESS indicates all I/Os were successfully aborted,
or the status SPDK_BDEV_IO_STATUS_FAILED indicates any I/O was failed to
abort by any reason.
spdk_bdev_abort() does not support aborting abort or reset request
due to the complexity for now.
Following patches will support I/O split case.
Add unit tests together to cover the basic paths.
Besides, ABI compatibility check required us to bump up SO version of
a few libraries or modules. Bump up SO version of blob bdev module simply
because it does not have any out-of-tree consumer, and suppress bumping
up SO version of lvol library because the affected struct spdk_lvol
is not part of public APIs.
