To be honest, I'm a little confused. Should we panic if quota
registration fails, or should it depend on the user's cmdline
parameters? Just like in the filesystem where we can choose
whether to panic in case of exceptions.

Or, should we panic if registration fails when
CONFIG_QUOTA && CONFIG_SYSCTL are enabled?

BTW, kindly ping for:
https://lore.kernel.org/lkml/20230228103515.sb6qpvnmbvenvq73@quack3/

Not sure if you have forgotten to pick these two commits.

Thx,
