Subject: [PATCH net 0/2] Fixes for clcsock shutdown behaviors

These patches fix issues when calling kernel_sock_shutdown(). To make
the solution clear, I split it into two patches.

Patch 1 keeps the return code of smc_close_final() in
smc_close_active(), which is more important than kernel_sock_shutdown().

Patch 2 doesn't call clcsock shutdown twice when applications call
smc_shutdown(). It should be okay to call kernel_sock_shutdown() twice,
I decide to avoid it for slightly speed up releasing socket.

Tony Lu (2):
  net/smc: Keep smc_close_final rc during active close
  net/smc: Don't call clcsock shutdown twice when smc shutdown
