It passed my test bed. Just FYI, the code in question is never exercised unless you see the message: load extent tree[%d] block at %d Somewhere in the boot. The reason is that if you keep a separate /boot partition, the chances are it has very few files, so those files it has are very contiguous and ext4 doesn't need to build an extent tree so our IPL code handles everything in ext3_extent_leaf_find(). The way to build a fragmented /boot is (starting with an empty /boot): mkdir /boot/tmp a=0; while dd if=/dev/zero of=/boot/tmp/block.${a} bs=16k count=1; do a=$[$a+1]; done a=0 while rm /boot/tmp/block.${a}; do a=$[$a+2]; done And then copy the kernels in.
