[PATCH 02/16] libnetfs: handle dead-name notifications |
Date: |

Handle dead-name notifications the same way libdiskfs does. In fact,
dead-name.c is a verbatim copy with trivial modifications. It clears
np->sockaddr if the dead name notification was for that port.
* libnetfs/dead-name.c: New file.
* libnetfs/Makefile (OTHERSRCS): Add dead-name.c.
