Subject: Re: block/bsg.c

hrm.  uninitialized_var(x) does not silence the warning, on my compiler:

[jgarzik@...tzel misc-2.6]$ rpm -q gcc
gcc-4.1.2-13.fc6

@@ -1358,6 +1358,8 @@ udf_load_partition(struct super_block *sb, 
kernel_lb_addr
                         {
                                 kernel_lb_addr ino;

+ 
uninitialized_var(ino.partitionReferenceNum);
+
                                 if (!UDF_SB_LASTBLOCK(sb))

still yields

uninitialized in this function
