Are you suggesting making this sysctl sticky? Are there any examples of how to implement a sticky sysctl that can take more than 2 values in case we want to add an intermediate level that still allows privileged processes to use io_uring? Also, what would be the use case? Preventing privileged processes from re-enabling io_uring? Thanks! -- Matteo
