Subject: New compiler warning in 2.6.34-rc1: 'start_ext.ee_block' may be used
 uninitialized

Hi,

I saw the following scroll by during kernel compilation:

fs/ext4/move_extent.c: In function 'mext_leaf_block':

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


Is it real?  It seems that the initial start_ext.ee_len = 0 guards
against accidental use of an uninitialized start_ext.ee_block, but maybe
I missed something.

The message is from gcc (Gentoo 4.3.4 p1.0, pie-10.1.5) 4.3.4 here.
