And these deadlocks aren't possibly related to the introduction of FMODE_ATOMIC_POS, and hence would be resolved by https://patchwork.kernel.org/patch/8752411/(or something along those lines, if nonseekable_open() isn't used on that code path)? I ask because we had a similar report, but when I put together the (refused upstream) patch I assumed the files under /dev wouldn't have the same issue (and I still didn't check whether they would).
