Subject: Re: [PATCH] ext4: reject inline data flag when i_extra_isize is zero

Looking at the syzbot logs more carefully, I see the initial 'acceptance' was 
because the filesystem failed to mount ('VFS: Can't find ext4 filesystem'), 
so the bug couldn't be triggered at all. My patches were never actually tested 
against the real bug.

I apologize for the confusion. I still cannot test locally to determine what 
the actual corruption scenario is. Today I have re-tested my same patch in 
syzbot and it is failing.

Best regards,
Deepanshu
