Zhe Weng 817a43de4d net: Add FIOC_FILEPATH ioctl support for tcp/udp/local sockets 
Example of /proc/PID/group/fd, which prints the file path:

FD  OFLAGS  TYPE POS       PATH
0   3       1    0         /dev/console
1   3       1    0         /dev/console
2   3       1    0         /dev/console
3   3       9    0         udp:[0.0.0.0:10197<->114.118.7.163:123, tx 0/16384, rx 0/16384, flg 1]
4   1027    9    0         tcp:[0.0.0.0:23<->0.0.0.0:0, tx 0/16384, rx 0/16384 + ofo 0, st 01, flg 31]
