           Summary: renaming socket in use does not update /proc/X/fd
           Product: File System
           Version: 2.5
    Kernel Version: 3.2.0-26 ubuntu
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: low
          Priority: P1
         Component: ext4
        AssignedTo: fs_ext4@...nel-bugs.osdl.org
        ReportedBy: wolfgang@...dewald.de
                CC: wolfgang@...dewald.de
        Regression: No


normally, renaming a file in use updates its name in /proc/X/fd

but this does not work for sockets. And so fuser fails to tell me
about the process using the socket when renamed.

using ext4 of course

i5:~/.kajonggserver$ fuser socket
/home/wr/.kajonggserver/socket: 27557
i5:~/.kajonggserver$ l /proc/27557/fd/3
lrwx------ 1 wr wr 64 Jul 18 22:00 /proc/27557/fd/3 -> socket:[1344224]
i5:~/.kajonggserver$ mv socket X
i5:~/.kajonggserver$ fuser X
i5:[Exit 1 (SIGHUP)]~/.kajonggserver$ l /proc/27557/fd/3
lrwx------ 1 wr wr 64 Jul 18 22:00 /proc/27557/fd/3 -> socket:[1344224]
