The "Asynchronous device registration (EXPERIMENTAL)" Kconfig option is for 2+ years, it is used when registration takes too much time for massive amount of cached data, to avoid udev task timeout during boot time. Many users and products enable this Kconfig option for quite long time (e.g. SUSE Linux) and it works as expected and no issue reported. It is time to remove the "EXPERIMENTAL" tag from this Kconfig item.

config BCACHE tristate "Block device as cache" select BLOCK_HOLDER_DEPRECATED if SYSFS select CRC64 help Allows a block device to be used as cache for other devices; uses a btree for indexing and the layout is optimized for SSDs.
See Documentation/admin-guide/bcache.rst for details.
config BCACHE_DEBUG bool "Bcache debugging" depends on BCACHE help Don't select this option unless you're a developer
Enables extra debugging tools, allows expensive runtime checks to be
turned on.
config BCACHE_CLOSURES_DEBUG bool "Debug closures" depends on BCACHE select DEBUG_FS help Keeps all active closures in a linked list and provides a debugfs interface to list them, which makes it possible to see asynchronous operations that get stuck.
config BCACHE_ASYNC_REGISTRATION bool "Asynchronous device registration" depends on BCACHE help Add a sysfs file /sys/fs/bcache/register_async. Writing registering device path into this file will returns immediately and the real registration work is handled in kernel work queue in asynchronous way.
