This is from mainline kernel.
commit 06693f305e60202d2795a10bee7fb7da23bc2acc
Merge: 75eaff0 a661b43

Thanks for report! I'd need full disassebly of jbd2_journal_file_inode()
function but guessing from decoding instructions around the place where we
oopsed I think we passed NULL jinode into jbd2_journal_file_inode() -
likely this was introduced by 0713ed0cde76438d05849f1537d3aab46e099475.

Hum... jinode gets attached to ext4_inode_info in ext4_file_open(). But
here we entered that path via sys_truncate() so ext4_file_open() didn't get
called. OK, so we need to attach jinode to ext4_inode_info somewhere in
truncate and punch hole paths. I'll prepare a patch for that.
