- fix deadlock between iget/srcu lock/synchronize srcu while freeing an
  inode

- fix double lock on subvolume cross-rename

- tree log fixes
  - fix missing data checksums after replaying a log tree
  - also teach tree-checker about this problem
  - skip log replay on orphaned roots

- fix maximum devices constraints for RAID1C -3 and -4

- send: don't print warning on read-only mount regarding orphan cleanup

- error handling fixes
