[$] ioctl() forever?

In a combined storage and filesystem session at the2022 Linux Storage,Filesystem, Memory-management and BPF Summit (LSFMM), Luis Chamberlainand James Bottomley led a discussion about the use of ioctl()as a mechanism for configuration. There are plenty of downsides to the useof ioctl() commands, and alternatives exist, but in general kerneldevelopers have chosen to continue using this multiplexing systemcall. While there is interest in changing things, at least in somequarters, the discussion did not seem to indicate major changes on the horizon.
