Merge tag 'bcachefs-2025-04-03' of git://evilpiepirate.org/bcachefs

Pull more bcachefs updates from Kent Overstreet:
 "More notable fixes:

   - Fix for striping behaviour on tiering filesystems where replicas
     exceeds durability on destination target

   - Fix a race in device removal where deleting alloc info races with
     the discard worker

   - Some small stack usage improvements: this is just enough for KMSAN
     builds to not blow the stack, more is queued up for 6.16"
