Takamori Yamaguchi b0a8cc58e6 mm: bugfix: set current->reclaim_state to NULL while returning from kswapd() ... In kswapd(), set current->reclaim_state to NULL before returning, as current->reclaim_state holds reference to variable on kswapd()'s stack. In rare cases, while returning from kswapd() during memory offlining, __free_slab() and freepages() can access the dangling pointer of current->reclaim_state.
