In a combined storage and filesystem session at the
2022 Linux Storage,
Filesystem, Memory-management and BPF Summit (LSFMM), Luis Chamberlain
and James Bottomley led a discussion about the use of ioctl()
as a mechanism for configuration. There are plenty of downsides to the use
of ioctl() commands, and alternatives exist, but in general kernel
developers have chosen to continue using this multiplexing system
call. While there is interest in changing things, at least in some
quarters, the discussion did not seem to indicate major changes on the horizon.
