An example output:
$ ./lsfd -p 3101482 -Q '(FD > 2)'
COMMAND PID USER ASSOC XMODE TYPE SOURCE MNTID INODE NAME
test_mkfds 3101482 yamato 3 rw---- eventpoll anon_inodefs 15 106 tfds=4,5
test_mkfds 3101482 yamato 4 r----m CHR mem:8 23 8 /dev/random
test_mkfds 3101482 yamato 5 -w---m CHR mem:8 23 8 /dev/random
The fd 4 and 5 is multiplexed by 3, an evetpoll fd.
Therefore 'm' flags in XMODE column for fd 4 and 5 are set.
Just one character but 'm' may help users to understand the "IO structure"
of a process.

What about also adding a MULTI column and printing the number of the multiplexing FD there? ;-) |
