The (compressed) crafted image which causes crash
- Overview
When mounting the attached crafted image and making a new file, I got this
error and the error messages keep repeating.
The image is intentionally fuzzed from a normal f2fs image for testing and I
run with option CONFIG_F2FS_CHECK_FS on.
- Reproduces
mkdir test
mount -t f2fs tmp.img test
cd test
touch t
