Subject: [PATCH 1/6] ext4: remove unnecessary var in ext4_ext_insert_extent
Date: Thu, 17 Nov 2011 10:03:20 +0800 [thread overview]
Message-ID: <1321495405-9583-1-git-send-email-xiaoqiangnk@gmail.com> (raw)
Var(uninitialized) is not necessary. As the comment says,
two extent are either initialized or uninitialized. So
checking newext is ok.
