Subject: ext4: Fix coding style in fs/ext4/move_extent.c
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c26d0bad3d0e951487e5dee36632dd3817f42b10;p=openwrt%2Fstaging%2Fblogic.git

ext4: Fix coding style in fs/ext4/move_extent.c

Making sure ee_block is initialized to zero to prevent gcc from
kvetching.  It's harmless (although it's not obvious that it's
harmless) from code inspection:

fs/ext4/move_extent.c:478: warning: 'start_ext.ee_block' may be used
uninitialized in this function

Thanks to Stefan Richter for first bringing this to the attention of
linux-ext4@vger.kernel.org.
