    SubjectRe: [PATCH] kernel/futex.c: Uneeded memory barrier

    Or eliminate the macro altogether, and create set_current_interruptible()
    and set_current_uninterruptible() which have the barrier, and let the normal
    users do the assignment the way God intended 8)

    In practice, those who care are using __, the rest aren't critical.
