Subject: [PATCH 3/3] Ext2: remove the static function release_blocks to optimize the kernel
Date: Wed, 06 Feb 2013 12:03:23 -0800	[thread overview]
Message-ID: <5112B70B.7020805@gmail.com> (raw)

From: Wang Shilong <wangsl-fnst@cn.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.
