Linus Torvalds e6861be452 More bcachefs bugfixes for 6.7

Bigger/user visible fixes:
 
  - bcache & bcachefs were broken with CFI enabled; patch for closures to
    fix type punning
 
  - mark erasure coding as extra-experimental; there are incompatible
    disk space accounting changes coming for erasure coding, and I'm
    still seeing checksum errors in some tests
 
  - several fixes for durability-related issues (durability is a device
    specific setting where we can tell bcachefs that data on a given
    device should be counted as replicated x times )
 
  - a fix for a rare livelock when a btree node merge then updates a
    parent node that is almost full
 
  - fix a race in the device removal path, where dropping a pointer in a
    btree node to a device would be clobbered by an in flight btree write
    updating the btree node key on completion
 
  - fix one SRCU lock hold time warning in the btree gc code - ther's
    still a bunch more of these to fix
 
  - fix a rare race where we'd start copygc before initializing the "are
    we rw" percpu refcount; copygc would think we were already ro and die
    immediately
