Apart from last block group trimming issue, something is wrong
when size is bigger than 500000k.
This loop runs for long with no errors:
while true; do
kilobytes=$(( (RANDOM*RANDOM) % 500000 + 60))
test_mke2fs || exit 1
done
while this one finds bad size rather quickly:
while true; do
kilobytes=$(( (RANDOM*RANDOM) % 500000 + 60))
test_mke2fs || exit 1
done
The diff says inode count is wrong:
# ./mkfs_ext2_test.sh
