Just trying space_cache=v2 on my big backup btrfs, mounted via
space_cache=v2,enospc_debug,nofail,noatime,compress=zlib. Looks like
something got confused during an rsync which then quickly propigated
up to forcing the fs read-only in the long stack traces below. I'll be
happy to test the new ENOSPC ticket system patches once they seem
ready if it will help. btrfs file usage:
