Subject: [PATCH 3/3] Ext2: remove the static function release_blocks to optimize
the kernel
From: Wang Shilong <wangsl-fnst@...fujitsu.com>
Because the static function 'release_blocks' is only called
when releasing blocks,it will be more simple and efficient to
call the function 'percpu_counter_add' directly.
