The Realtek RTL8723BS WiFi driver, added to the Linux kernel staging area back in 2017 with Linux 4.12, is still undergoing cleanup work nearly a decade later. For Linux 7.2, the staging pull request is dominated by 154 patches targeting this driver, described by Greg Kroah-Hartman as a 'beast of a driver.' The patches focus on removing function wrappers, cleaning up code, renaming functions, and eliminating unnecessary abstractions to bring the driver in line with upstream Linux WiFi driver standards. The RTL8723BS supports 802.11 b/g/n WiFi and Bluetooth 4.0, and the goal remains graduating it from the staging area into the formal networking subsystem.
