[PATCH 3/5] mm/slab: move cache_flusharray() out of unlikely.text section

From: Joonsoo Kim
Date: Thu Aug 21 2014 - 04:10:54 EST


Now, due to likely keyword, compiled code of cache_flusharray() is
on unlikely.text section. Although it is uncommon case compared to
free to cpu cache case, it is common case than free_block(). But,
free_block() is on normal text section. This patch fix this odd situation
to remove likely keyword.
