[Qemu-devel] [PATCH] NBD dead code elimination

[Carlo Marcelo Arenas Belon <carenas@sajinet.com.pe>]

[-- Attachment #1: Type: text/plain, Size: 272 bytes --]

The following patch, removes tcp_socket_outgoing which is not being used by
the current implementation, neither the proposed unix socket patches.

This avoids the following compile time warning :

  nbd.c:99: warning: 'tcp_socket_outgoing' defined but not used
