Date: Fri, 21 Sep 2012 13:51:18 +0800 From: Wei Yongjun <weiyj.lk@...il.com> To: dushistov@...l.ru Cc: yongjun_wei@...ndmicro.com.cn, linux-kernel@...r.kernel.org Subject: [PATCH] ufs: fix return value check in ufs_alloc_lastblock() From: Wei Yongjun <yongjun_wei@...ndmicro.com.cn> In case of error, the function ufs_get_locked_page() returns ERR_PTR() or NULL pointer. The IS_ERR() test in the error handling should be replaced with IS_ERR_OR_NULL(). dpatch engine is used to auto generated this patch.
