It gets stranger. If I issue a 'sync' command, chances are the
defragment command will work. If I issue a bunch of them (in series,
however), then I get ENOSPC.
find /var/cache -xdev -type d -exec btrfsprogs -d {} \;
Seems to do it every time, with or without -depth. I get 100% success
and then 100% failure - no mixing.
