Date: Thu, 26 Jan 2012 14:55:03 -0800 From: Wang Shilong <wangshilong1991@...il.com> To: tytso@....edu CC: linux-ext4@...r.kernel.org Subject: [PATCH] Ext4: remove a useless check for the function ext4_data_block_valid From: Wang Shilong <wangsl-fnst@...fujitsu.com> Because it is no doubt 'start_blk + count < start_blk' always comes to false. It is useless to have this check,remove it.
