Re: [PATCH net 1/2] net/smc: Keep smc_close_final rc during active close

On 25/11/2021 07:19, Tony Lu wrote:

When smc_close_final() returns error, the return code overwrites by
kernel_sock_shutdown() in smc_close_active(). The return code of
smc_close_final() is more important than kernel_sock_shutdown(), and it
will pass to userspace directly.

Fix it by keeping both return codes, if smc_close_final() raises an
error, return it or kernel_sock_shutdown()'s.
