[GIT PULL] more bcachefs fixes

[Kent Overstreet <kent.overstreet@linux.dev>]

Hi Linus, some more bcachefs fixes. Nothing too crazy to report,
changelog should have it all.

Cheers,
Kent

  bcachefs: Extra kthread_should_stop() calls for copygc (2023-11-28 22:58:23 -0500)

----------------------------------------------------------------
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
