[PATCH v2 06/10] dm vdo: Update min_heap_callbacks to use default builtin swap

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

 



Replace the swp function pointer in the min_heap_callbacks of dm-vdo
with NULL, allowing direct usage of the default builtin swap
implementation. This modification simplifies the code and improves
performance by removing unnecessary function indirection.
