[GIT PULL] bcachefs fixes for 6.10-rc4

[Kent Overstreet]

Hi Linus, another batch of fixes for you. Nothing terribly exciting, the
usual mix of syzbot + user bug fixes.

The following changes since commit 83a7eefedc9b56fe7bfeff13b6c7356688ffa670:

  bcachefs: Fix rcu_read_lock() leak in drop_extra_replicas (2024-06-11 18:59:08 -0400)

----------------------------------------------------------------
bcachefs fixes for 6.10-rc4

- 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

  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
