Thanks!
Will read into.
While digging a little into the code I noticed that you have very few
checks of the on-disk data.
For example ->u.i_blkaddr. I gave it a try and created a
malformed filesystem where u.i_blkaddr is 0xdeadbeef, it causes the kernel
to loop forever around erofs_read_raw_page().
Thanks,
