Re: config PROC_CHILDREN

[Iago LÃpez Galeiras]

Hi Jean,

The purpose of this option is enabling /proc/<pid>/task/<tid>/children without
having to enable CHECKPOINT_RESTORE, which is hidden behind EXPERT.

Regarding its lack of help, documentation is in already in place[1] but perhaps
that's not clear for the user because as you say the Kconfig help text is missing.

I suggest adding something like:

    Provides a fast way to retrieve first level children pids of a task. See
    <file:Documentation/filesystems/proc.txt> for more information.

Do you think that's enough?

Thanks.
