    SubjectSplitting task-group stuff from task_struct
    Date

    Hi Linus, Andrew,

    Would you have any objection to task-group specific stuff being split from the
    task_struct and placed into a refcounted structure of its own and shared upon
    CLONE_THREAD.

    The fields I'm thinking of include:

    struct linux_binfmt *binfmt
    unsigned long personality
    pid_t tgid
    struct task_struct *group_leader
    u32 parent_exec_id;
    u32 self_exec_id;

    Should process credentials be shared?

    I could then add the process/session keyring pointers from my patch to it too.

    David
