syzbot is reporting possibility of deadlock due to sharing lock_class_key
for jbd2_handle across ext4 and ocfs2. But this is a false positive, for
one disk partition can't have two filesystems at the same time.

b97cb7d6a051aa6ebd57906df0e26e9e36c26d14 | Analyze and fix the following issue in the Linux kernel code: ext4: xattr: fix null pointer deref in ext4_raw_inode() | Problem Details:
If ext4_get_inode_loc() fails (e.g. if it returns -EFSCORRUPTED),
iloc.bh will remain set to NULL. Since ext4_xattr_inode_dec_ref_all()
lacks error checking, this will lead to a null pointer dereference
in ext4_raw_inode(), called right after ext4_get_inode_loc().

The cached ei->i_inline_size can become stale between the initial size
