Avoid uninitialized variant compile warning
When we compile btrfs-progs in RHEL5(with default gcc version 4.1.2 20070626), we can get following error: cc1: warnings being treated as errors btrfs-list.c: In function 'find_updated_files': btrfs-list.c:668: warning: 'disk_offset' may be used uninitialized in this function btrfs-list.c:667: warning: 'disk_start' may be used uninitialized in this function btrfs-list.c:666: warning: 'len' may be used uninitialized in this function make: *** [btrfs-list.o] Error 1 These varient are always initialized except inconsistent data in file system. We can set initial value for these variant for this situation. Signed-off-by: Zhao Lei <> Signed-off-by: Miao Xie <>
