    pids: kill signal_struct-> __pgrp/__session and friends · 1b0f7ffd
    Oleg Nesterov authored
    We are wasting 2 words in signal_struct without any reason to implement
    task_pgrp_nr() and task_session_nr().
    
    task_session_nr() has no callers since
    2e2ba22e, we can remove it.
    
    task_pgrp_nr() is still (I believe wrongly) used in fs/autofsX and
    fs/coda.
    
    This patch reimplements task_pgrp_nr() via task_pgrp_nr_ns(), and kills
    __pgrp/__session and the related helpers.
    
    The change in drivers/char/tty_io.c is cosmetic, but hopefully makes sense
    anyway.
