[Impact]
bcache_allocator() can call the following:
bch_allocator_thread()
-> bch_prio_write()
-> bch_bucket_alloc()
-> wait on &ca->set->bucket_wait
But the wake up event on bucket_wait is supposed to come from bch_allocator_thread() itself causing a deadlock.
[Test Case]
This is a simple script that can easily trigger the deadlock condition:
https://launchpadlibrarian.net/381282009/bcache-basic-repro.sh
A better test case has been also provided in bug 1796292 (duplicate of this bug):
https://bugs.launchpad.net/curtin/+bug/1796292/+attachment/5280353/+files/curtin-nvme.sh
[Fix]
Fix by making the call to bch_prio_write() non-blocking, so that bch_allocator_thread() never waits on itself. Moreover, make sure to wake up the garbage collector thread when bch_prio_write() is failing to allocate buckets to increase the chance of freeing up more buckets.
In addition to that it would be safe to also import other upstream bcache fixes (all clean cherry picks):

9951379b0ca88c95876ad9778b9099e19a95d566 bcache: never writeback a discard operation
[Regression Potential]
The upstream fixes are all clean cherry picks from stable (most of them are small cleanups), so regression potential is minimal.
The only special patch is "UBUNTU: SAUCE: bcache: fix deadlock in bcache_allocator()" that is addressing the main deadlock bug (that seems to be a mainline bug - not fixed yet). We should spend more time trying to reproduce this deadlock with a mainline kernel and post the patch to the LKML for review / feedback.
However, considering that this patch seems to fix/prevent the specific deadlock problem reported in this bug (tested on the affected platform) it can be considered safe to apply it.
