LKL is Linux Kernel Library. min_02.c is a program that calls lists of system calls in userspace and the craft image is a potentially faulty image to test error cases. We are going to release our source code so that you can build the ext4-combined shortly. We needs some clean-up inside the codes before making it public. I'm attaching stack dump at the last. I hope this could help you. Additionally I used Linux version 5.0.0+ for this trace (and in the linked ext4-combined binary) [ 0.050478] BUG: failure at fs/jbd2/commit.c:818/jbd2_journal_commit_transaction()!
