This patch consolidates socket option settings in nvmet-tcp by utilizing
the generic do_sock_setsockopt() helper for options including SO_LINGER,
SO_PRIORITY, SO_REUSEADDR, TCP_NODELAY, and IP_TOS. This change eliminates
the need to export and use specialized helpers for each individual socket
option.

Hmm.  I see that do_sock_setsockopt is exported, but it really should
not be.  It's really just an internal helper exposed for io_uring
and no modular code should be using it (never mind the non-GPL export).

Agreed. I am happy to remove the export, given it was introduced by my
change in commit 1406245c2945 ("net/socket: Break down
__sys_setsockopt")
