[patch 073/192] mm/swap_slots.c: delete meaningless forward declarations

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

Subject: mm/swap_slots.c: delete meaningless forward declarations

deactivate_swap_slots_cache() and reactivate_swap_slots_cache() are only
called below their implementations.  So these forward declarations are
meaningless and should be removed.
