ext4: add ext4-specific kludge to avoid an oops after the disk disappears The del_gendisk() function uninitializes the disk-specific data structures, including the bdi structure, without telling anyone else. Once this happens, any attempt to call mark_buffer_dirty() (for example, by ext4_commit_super), will cause a kernel OOPS. Fix this for now until we can fix things in an architecturally correct way.
