Comment 56 for bug 1796292

I've uploaded a new test kernel based on the latest bionic kernel from master-next:
https://kernel.ubuntu.com/~arighi/LP-1796292/4.15.0-56.62~lp1796292/

In addition to that I've backported all the recent upstream bcache fixes and applied my proposed fix for the potential deadlock in bch_allocator_thread() (https://lkml.org/lkml/2019/7/10/241).

I've tested this kernel both on a VM and on a bare metal box, running the test case from bug
1784665 (https://launchpadlibrarian.net/381282009/bcache-basic-repro.sh - with some minor adjustments to match my devices).

The tests have been running for more than 1h without triggering any problem (and they're still going).

Ryan / Chris: it would be really nice if you could do one more test with this new kernel... and if you're still hitting issues we can try to work on a better reproducer. Thanks again!
