Merge tag 'v6.12-rc4' into sched/core, to resolve conflict

Overlapping fixes solving the same bug slightly differently:

  7266f0a6d3bb fs/bcachefs: Fix __wait_on_freeing_inode() definition of waitqueue entry
  3b80552e7057 bcachefs: __wait_for_freeing_inode: Switch to wait_bit_queue_entry

Use the upstream version.
