io_uring_register_personality - register credentials with io_uring

#include <liburing.h>
int io_uring_register_personality(struct io_uring *ring);

The io_uring_register_personality(3) function registers the credentials of the calling application with the io_uring instance specified by ring. This allows a ring to be shared between separate users or processes while maintaining credential separation.

The returned personality ID can be used in the personality field of a submission queue entry to execute that request with the registered credentials.

Returns a positive personality ID on success that can be used in future operations. On error, a negative errno value is returned.
