    Subject[PATCH 0/2] restrict statistics information to user
    Date
    taskstats and /proc/PID/io may be used for gathering private
    information. E.g. for openssh and vsftpd daemons wchars/rchars may be
    used to learn the precise password length (pass_len = w_chars - CONST).
    Restrict it to user.

    The simplified proof learning whether ~*/.ssh/authorized_keys file
    exists is posted here:

    Vasiliy Kulikov (2):
    proc: restrict access to /proc/PID/io
    taskstats: restrict access to user
