Subject: [PATCH] proc: Expose /proc/<pid>/task/<tid>/children unconditionally
Date: Tue, 25 Jun 2013 12:51:45 -0700 [thread overview]
Message-ID: <0e00e9073855c02a382d49ba1ede9c4fda3451b7.1372189875.git.luto@amacapital.net> (raw)
This is currently only available if CONFIG_CHECKPOINT_RESTORE, which
is hidden under CONFIG_EXPERT. It's generally useful functionality,
though, so expose it unconditionally.
