Nah, not necessary:

RIP: 0010:[<ffffffff81355161>]  [<ffffffff81355161>] _raw_spin_lock+0x9/0x20
[<ffffffff8110d19e>] create_empty_buffers+0x43/0xae
[<ffffffffa030c003>] ext4_discard_partial_page_buffers_no_lock+0x9d/0x3ee [ext4]
[<ffffffffa030c60f>] ext4_da_write_end+0x231/0x2df [ext4]

093e6e3666f47d29763a235b404c84ee47ba8bb0
