Hi Jens,

Guoju Fang just posts a bug fix to solve a bcache journal deadlock.
This bug probably happens when system memory is in heavy usage,
the deadlock is observed occasionally for a long while.
If it is too late to go into Linux 4.19, I will submit to you in
4.20 merge window, but it will be cool to have it in this run.

Thanks.

Coly Li
