- fix kworker explosion, due to calling submit_bio() (which can block)
from a multithreaded workqueue
- fix error handling in btree node scan
- forward compat fix: kill an old debug assert
- key cache shrinker fixes
this is a partial fix for stalls doing multithreaded creates - there
were various O(n^2) issues the key cache shrinker was hitting
https://lore.kernel.org/linux-bcachefs/fmfpgkt3dlzxhotrfmqg3j3wn5bpqiqvlc44xllncvdkimmx3i@n4okabtvhu7t/
there's more work coming here; I'm working on a patch to delete the
key cache lock, which initial testing shows to be a pretty drastic
performance improvement
- assorted syzbot fixes
