    slab allocators: Remove SLAB_CTOR_ATOMIC · 4f104934
    Christoph Lameter authored
    SLAB_CTOR atomic is never used which is no surprise since I cannot imagine
    that one would want to do something serious in a constructor or destructor.
     In particular given that the slab allocators run with interrupts disabled.
     Actions in constructors and destructors are by their nature very limited
    and usually do not go beyond initializing variables and list operations.
    
    (The i386 pgd ctor and dtors do take a spinlock in constructor and
    destructor.....  I think that is the furthest we go at this point.)
    
    There is no flag passed to the destructor so removing SLAB_CTOR_ATOMIC also
    establishes a certain symmetry.
