    Of course, I know that you know about slab.h - you wrote it! :)

    I was talking about the new more recent usage of slab.h as something more
    than just interface header to your SLAB allocator. Namely it now serves as
    a header for declarations of SLAB caches used by more than one compilation
    unit.

    And if it is used by more than one compilation unit (and your
    sigact_cachep is) then it is visible system wide, i.e. it is not static to
    that compilation unit. It was a pollution to have single (or in pairs)
    "extern kmem_cache_t *bla_cachep" all over the place so I put some of them
    in slab.h next to the rest which were already there and that was accepted
    by Linus as cleanup (rather than adding to pollution).

    Tigran
