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.
James
