Hi,
normally, renaming a file in use does update 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.
why is that so?
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]
Linux i5 3.2.0-26-generic #41-Ubuntu SMP Thu Jun 14 17:49:24 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
I am keeping the process 27557 running should you want more info about that process
