Date: Tue, 14 May 2013 18:37:31 +0200 From: Lukas Czerner <lczerner@...hat.com> To: linux-mm@...ck.org Cc: linux-kernel@...r.kernel.org, linux-fsdevel@...r.kernel.org, linux-ext4@...r.kernel.org, akpm@...ux-foundation.org, hughd@...gle.com, lczerner@...hat.com Subject: [PATCH v4 17/20] ext4: remove unused code from ext4_remove_blocks() The "head removal" branch in the condition is never used in any code path in ext4 since the function only caller ext4_ext_rm_leaf() will make sure that the extent is properly split before removing blocks. Note that there is a bug in this branch anyway. This commit removes the unused code completely and makes use of ext4_error() instead of printk if dubious range is provided.
