Pull bcachefs fixes from Kent Overstreet:

 - Some fixes to help with filesystem analysis: ensure superblock
   error count gets written if we go ERO, don't discard the journal
   aggressively (so it's available for list_journal -a)

 - Fix lost wakeup on arm causing us to get stuck when reading btree
   nodes

 - Fix fsck failing to exit on ctrl-c

 - An additional fix for filesystems with misaligned bucket sizes: we
   now ensure that allocations are properly aligned

 - Setting background target but not promote target will now leave that
   data cached on the foreground target, as it used to

 - Revert a change to when we allocate the VFS superblock, this was done
   for implementing blk_holder_ops but ended up not being needed, and
   allocating a superblock and not setting SB_BORN while we do recovery
   caused sync() calls and other things to hang

 - Assorted fixes for harmless error messages that caused concern to
   users
