[RESEND PATCH] pty: show associative slave of ptmx in fdinfo

2017-05-24 Thread Masatake YAMATO
This patch adds "tty-index" field to /proc/PID/fdinfo/N if N specifies /dev/ptmx. The field shows the index of associative slave pts. Though a minor number is given for each pts instance, ptmx is not. It means there is no way in user-space to know the association between file descriptors for pts/n
